What are /r/APStudents' favorite Products & Services?

From 3.5 billion Reddit comments

Speaking of using a VPN, Id like to tell you about today’s sponsor: NordVPN. Trust NordVPN to protect YOUR data from prying eyes, and circumvent annoying location restrictions. Use offer code ‘APStudents’ for 40% off your first month by following the link in the description.

If anyone is looking for a last minute safe method (not giving your password to a website) to do this, I downloaded the TunnelBear chrome browser extension which has 500MB of data free, so way more than enough. I keep changing servers until I get one hosted in California (seemed to be about every third server) so that's what I am going to do this morning.

Absolutely. UNDER NO CIRCUMSTANCES DOWNLOAD HOLA. It is malicious and will give your IP address to someone else.

TunnelBear works pretty well. It gives you 300MB free, which is more than enough to check your scores.

If you want to skip the hassle of a VPN: or

If you want to control where you put your password: TunnelBear, StarVPN (iOS)

If you're really paranoid about security: just wait for your day

yes but you have to go enable it in settings. safari -> preferences -> advanced -> show develop menu

this site explains it with pictures if u want

If you were worried about earlyscores like myself, you can just use a VPN.

​

I went with ProtonVPN because it's free and actually still works after the 1 week free trial. I think you still have to pay for stuff like NordVPN and the like. If you go with ProtonVPN, pick the US 2 server, that's the California one.

​

Goodluck and get 5's.

Serotonin. SSRIs are routinely prescribed to patients with OCD.

Take Zoloft, for example (from WebMD):

“Sertraline is used to treat depression, panic attacks, obsessive compulsive disorder...”

Academus>>>>>>>> It’s an app that a few kids at my school made that hooks up to your StudentVUE and turns it into a much better interface that gives you notifications when assignments go in.

iOS Android

Math courses: Finish about a month early and do mock exams and practice problems. Also, learn your calculator for stats.

Lang and Comp: Practice Practice Practice all the time. Write often, write well, and sometimes write timed. Practice makes perfect, but it's not good to practice poorly.

AP Physics: Practice all sorts of scenarios. Go here and do the practice problems. Then, get a study book and do the mock tests and practice problems.

APUSH: Study the textbook and a prep book. You will need to know the areas that both emphasize separately. Additionally, study secondary and especially primary sources. You will need to know outside sources for the exam; they earn you points on the free response and prep you for the stimulus questions. You may also want a study book.

APUSGP: Not sure. Don't have the course.

Anything memorization based: Use Anki. I hear it saves med school students' lives.

My site should work well :P but there are lots of great free VPN sites out there, personally one I've used is https://strongvpn.com which has a New York location.

Here's a free one, I am sure it would also work well: http://vpnip.net/america-vpn/

The Pearson-Holtzclaw review book that accompanies the Campbell textbook is hands down the best review book for AP Bio. Here's a link to it on Amazon:

https://www.amazon.com/Preparing-Biology-School-Pearson-Education/dp/0133458148

I got you, here's a list.

I used the Avast one with the 7 day trial, it works fine for me. Barring that, NordVPN is your best option, but you can only get a free trial of that without credit card on mobile.

Of course, if all else fails, EarlyScores is still there.

EDIT: Make sure you pick one where you can choose an option in one of the states like Texas! I know you can with the Avast in Nord ones.

The difference between a VPN company and an unofficial website is that the whole VPN company's business model is predicated on the idea of keeping your data private and safe while an unofficial website has no obligation to anyone.

If a VPN company states that they will protect your privacy and then does the opposite of that (for example, by selling your data to third-parties), they will lose business (and eventually cease to exist) because people will not trust them anymore and thus will not use them anymore. Now, that doesn't mean that all VPN companies treat your data in the same way (for example, ExpressVPN does store logs, which could later be used against you), but that is why it's important to read the privacy policies of the VPN companies before you use their VPN and to make sure that the VPN company is reputable. There are some people who make fake VPNs just to take your data and sell it, but that is why you also need to make sure you know what you're getting into it.

For anyone thinking about using a VPN, use this comparison chart to help you figure out which one is the best. and they are a reputable VPN company that doesn't engage in any practices like keeping logs.

Are you sure the vpn you chose is making you appear specifically in one of the east coast states getting scores today. Try VyprVPN and select New York, thats the one I used, or use one of those websites like

This guy is bitter because AP-1 is conceptual and you can't plug and chug. AP 1 is about actually understanding how Newtonian mechanics works, and calculus really isn't integral (heyo) to that. It makes a few things kinda easier, but for the most part AP-1 is very little math, and is instead a significant amount of manipulation of variables and understanding mathematical modeling. HOWEVER, it is still do-able if you're able to pick up on physical understanding quickly. There's an edx course on here that gets posted a lot that could help you gauge your ability. I'll try to find it in a second.

Here's the thing - I only know one school that gives credit for AP Physics 1, and it's general elective credit unless you get a 5, so make sure your school would actually give you credit before you waste time on it.

EDIT: Sorry, it's an Udacity course. https://www.udacity.com/course/intro-to-physics--ph100

Your teacher is correct. You don't need a deep understanding before you take it if AP Physics C Mechanics is a two semester course. You would if it was a 1 semester course-- but the extra time means AP Physics C can be first exposure.

But lots of kids find physics hard. So some light summer prep is not a bad idea. I like udacities archived class: https://www.udacity.com/course/intro-to-physics--ph100 It gives you a nice light algebra based run through a lot of topics. It's not deep and they definitely don't ask complicated versions of problems. But your goal shouldn't be to learn all of Physics C to prep for Physics C. Just to learn enough to make it come a bit easier when your teacher goes in depth.

2nd fundemental theorem of calc:

\frac{d}{dx}\int_v^uf\left(t\right)dt=f\left(u\right)du-f\left(v\right)dv < put that into desmos.

basically the derivative of the integral of f(t) dt from v to u is equal to f(u)du - f(v)dv (usually v is a constant and so dv = 0 so there is no subtracting part).

You didn't give the book author so I'm not sure that this is the right one, but here's the one by Birdsall Viault. If it's not right, then search on Library Genesis for the author you want and I give it a 95% chance it'll be there.

Use an exit address in either Florida, Louisiana, Mississippi, or Texas. I use AirVPN so I have Texas available to me. I'd honestly just use earlyscores at this point since they're well known and haven't been shitty (yet... who knows). Easier than fussing with VPNs

Use a VPN!

Try using TunnelBear, they have a free trial that requires only an email. Refresh the server until you get one hosted in California (usually you get New York or California), and check your scores that way.

Personally I'm using IPVanish, but that's a $10/month dedicated VPN that I already had. As far as paid VPNs go tho, IPVanish is pretty awesome. Location selection, nice GUI, no noticeable latency. Paid are only worth it tho if you torrent as many movies as I do.

If you're having trouble with a VPN you can try using the Opera browser. Opera uses SurfEasy in its built in browser, although you cant select your region if you use the browser rather than the VPN itself. If you're unsure of your location in the US you can just search for your IP location on Google. If your location isn't in an Eastern state, restart the browser and try again.

As a summation of my AP career: Human Geography-5 APUSH-5 Music Theory-5 English Language-5 English Literature-5 Spanish Language-5 Stats-... 3

Math is not my forte; I've always preferred language and history. I wish I could have made it out with all 5s, but that's alright. I used the app SuperVPN to see my scores. I tried it again and couldn't access my scores this time, but I think it will probably work later today. Best of luck in accessing scores!

I have programming experience, but only with languages other than Java, so this might be a little inaccurate. I basically looked up the Java documentation online and read it through to understand the syntax of the language, and I did a bunch of practice problems on this really great website called codingbat.com. I'd use CodeAcademy if you're just starting out with no experience, and accompany it with an actual Java programming book rather than an AP prep book. I borrowed the Barron's book from my friend and did the practice tests, and they really help for multiple choice since the questions aren't something you'd expect if you don't practice. "Head First Java" is a really great book for beginner programmers. However, the most important thing is to just practice. Don't just practice AP style problems and think you'll do fine, because the free-response portion tests pure programming skill. I started with CodingBat, then gradually worked my way up to Google CodeJam problems, and those really helped strengthen the areas I'm proficient at and enhance the areas that I needed to work on. Might be kind of unclear since I'm really tired right now, but hope it helped.

How much reading? In APUSH we had 30 pgs every night. If its like APUSH I rather not do it cause the textbook was poor. I rather read books with the left over time I have from doing regular that I want to read like "The Art of War".

I took both and can tell you that they are two very different exams. The AP exam is more conceptual based--less factual regurgitation happening there. However, the SAT II is, in contrast, mostly factual based. You gotta get your memorization down.

There is a lot of plant stuff on there which, IIRC, isn't stressed in AP Bio, and is sometimes skipped altogether. Dont confuse what I said with photosynthesis, I'm talking about like parts of the plant (ex: apical meristem, plant classifications).

The SAT II is also easier to study for since you pretty much know what's going to be on the exam. The exam is all multiple choice (like all subject tests) and the questions are a bit different than the AP multiple choice. The beginning of the test will usually provide you with an image, which you then have to label with the choices they give you. That's just blunt memorization right there. The rest of the questions really don't stress concepts.

I remember one that gave me a picture of the heart and asked me to label the major sections (vena cava, right/left atrium, ventricles, etc.) Another question gave me a choices of 4 animals and asked me which one was a reptile. No joke. (That doesnt mean the test is easy though...)

This exam is the only real SAT II Bio released by CollegeBoard. Take a look at it and you will see what I mean--it is very different from the AP. Time yourself, practice with it, and see what you get. If you want the book where its from, here you go.

I recommend taking the Molecular Biology test, since that's essentially the core of what you did in AP. Ecological is easier, but looked as less favorably in admissions.

For APUSH, I really recommend the AMSCO review book. Here's a link: http://www.barnesandnoble.com/mobile/w/united-states-history-john-j-newman/1101755236?ean=9781682404553&amp;pcta=n&amp;st=PLA&amp;sid=BNB_DRS_Core+Shopping+Textbooks_00000000&amp;2sid=Google_&amp;sourceId=PLGoP109&amp;k_clickid=3x109

For AP Calc AB, I would recommend the Princeton Review book

Do you know if the Princeton review book or the REA's crash course (http://www.barnesandnoble.com/p/ap-european-history-crash-course-book-online-larry-krieger/1121748756/2673305802860?st=PLA&amp;sid=BNB_DRS_Marketplace+Shopping+greatbookprices_00000000&amp;2sid=Google_&amp;sourceId=PLGoP24184&amp;k_clickid=3x24184) is good enough for a 5? I'm starting to panic b/c I haven't really prepped too much but I still want to do well.

Take whichever one interests you more. If you do pick AP Physics 1 and are nervous about it, do this online course self paced the summer before.
https://www.udacity.com/course/intro-to-physics--ph100 It's not too long, the problems aren't hard; you don't get a lot of repetition. So you won't know material well enough to get an A based on the class. But it will familiarize you with just enough to put you a half-leg up on other students in the class. A half-leg up on other students is amazingly helpful in physics.

During the course, resources organized by topics (like Khan Academy or flipping physics) tend to be better.

I always hesitate to suggest someone take "C" if they have not taken any physics before. Depending on you, it might be possible, or it might be hell.

If you decide to take Physics C, self teach the following the summer before: 1) Learn rule for derivatives of polynomials, by rote. (That is d (x^n)/dy = n x^(n-1). 2) Learn rule for derivative of sin and cos. (d cosθ/dt = -sinθ ; d sinθ/dt = cosθ ) 3) Learn rule for integrating (i.e. "undifferentiating") polynomials and sin and cos.) 4) When learning integrating, understand about applying limits of the integral or including an arbitrary constant.

You can defer learning why the rules are true. You'll get that in math and you don't need it for calculus.

If you've never taken physics and you have time do the somewhat painless Udacity online course: https://www.udacity.com/course/intro-to-physics--ph100 during the summer before. It's not too painful or repetitive, it's structured and it can give you the step up you need to avoid going into physics C with zero basis when other students are coming from AP Physics 1. (The class at your high school will be more intense than the online course, but something is better than nothing!)

As an physics tutor, I think so too. I also find the idea that logic vs. math are "either or".

Applications of physics to complicated geometries or generalizing to many situations can require a lot of math. That's not what AP Physics 1 focuses on. AP Physics 1 specifically avoids mathematically cluttered problems and derivations. One can show that you get a certain result starting from the equations and doing it that way. Or one can avoid it. Likely doing both helps. The idea that it's important to base your understanding in math.. that's nonsense.

That said: I have been hired by parents of students whose teachers are doing "math, math, math" when teaching AP Physics 1 classes.

It is impossible for someone on reddit to tell you what your AP Physics 1 class will emphasize because some teacher do accept the more conceptual philosophy of the AP Physics 1 and some do not.

That said: if a kid is planning to "self teach" in preparation for the AP Physics 1, I recommend https://www.udacity.com/course/intro-to-physics--ph100 which pretty painless, and gives you a layer that is both somewhat conceptual with enough applications to learn. Skip the experiments. Find the extra homework and do it. If you get stuck, ask people on reddit for explanations. (Explainers are lurking.)

This strategy is a modest goal, which is reasonable if your idea is to give yourself a base to "prep" a little. (Your goal should not be cram all of AP Physics 1 in the summer by yourself. You will fail.)

If after going through that course you still have time then start at the beginning with a prep book, Kahn academy etc. But most likely, you'll have a good base for starting whatever your school does for AP Physics 1.

Barron's is what my teacher recommended, so here's a copy if you need it. There's reading practice in the prep book, but for best results, use the CollegeBoard progress checks once your teacher opens them for you.

Just in case someone doesn't have a Java Compiler and doesn't have a lot of time to set up stuff, repl.it works beautifully for running Snippets of Code. It ain't gonna replace Netbeans and stuff, but it comes pretty close.

In case you needed a textbook for Physics C and not Physics 1+2, I would recommend University Physics, downloadable here as a PDF with the solution manual downloadable here, also as a PDF.

/u/Fgilan said it well, I found this book very useful (calculus made easy) https://www.google.com/url?sa=t&amp;source=web&amp;rct=j&amp;url=https://www.gutenberg.org/files/33283/33283-pdf.pdf&amp;ved=0CGMQFjAMahUKEwjhueWj1erGAhUFKYgKHRYpAQk&amp;usg=AFQjCNGkXg2OOYsgaw8t3sEyzLdBY8x72w&amp;sig2=_X6Rn1tFLe9G7ajkcMVj0w

Oh, of course! Sorry, my bad for misunderstanding you consistently.

A graphing calculator is used to complete most problems in stat, so a graphing calculator is very important. If you're lucky your teacher may have a class set of graphing calculators that can be borrowed.

There is a free alternative to a graphing calculator that can be used on a computer or android phone (just don't expect to be able to use this on any tests): http://wabbitemu.org/

Seems like my 2,3, and 4 are pretty identical to yours. My #1 solves the problem, but I didn't utilize any lists. Is it possible they'll deduct points for using regular arrays?

I used two AP reviews books at the same time and made notes in the margins. You can probably find a bunch of AP study guides online (especially on ISSUU):

http://issuu.com/yummycalorie/docs/cliffsap-united-states-history-3ed/202

For AP CSA I used this textbook: Java How To Program, Late Objects 11th Edition

Imo, I thought it was a bit overkill for the purposes of the AP CSA Exam. My course required that I used that textbook to supplement the learning, but it covered more than was needed for the exam, so that could be why. I would say the Barron's AP Comp Sci Review Book was really good overall for preparation, as it offered questions that were quite accurate in terms of the content and scope of the exam. Take this with a grain of salt, as I took the digital exam in administration 3, so it would likely differ from a pencil/paper exam.

&#x200B;

For AP Chem textbooks, the openstax chemistry textbooks, libretexts online textbooks, and Zumdahl would be the best. Again, I didn't find myself using textbooks very frequently unless it was a topic I needed more support on. I would recommend utilizing the AP Classroom resources (AP Daily Videos) for the most part, and relying on the Princeton Review Book for some prep. I used the Princeton Review Premium Prep book for AP Chem and found it worked sufficiently well in preparing for the unit tests at school, as well as in final preparation for the exam.

I recommend AP Physics Essentials written by Dan Fullerton. (Amazon) He also has a whole bunch of YouTube videos for AP Physics 1.

I'm using The Smartypants' Guide to Environmental Science for self study Here on Amazon; could also find on online maybe https://www.amazon.com/Smartypants-Guide-Environmental-Science-Exam/dp/1411644778

5 steps to 5 pdf online somewhere. Not currently using it, but it's free, the more the better I guess. https://drive.google.com/drive/folders/0B3RVreGMg1lQajVteUl2SzJnZHM

Also PR and Barron's, but someone said Smartypants' was all you needed for environmental science.

You can’t deliberately change it to California. TunnelBear has 1 IP in NY and 1 IP in Cali

Here are the steps u should follow: 1. After u download TunnelBear and set up ur account, connect to the USA tunnel. 2. Go to ur web browser and log into college board to view ap. 3. If that doesn’t work disconnect from the USA tunnel and reconnect back to it. 4. Try logging into ur collegeboard account again. 5. Repeat steps 3-4 if it still doesn’t work.

Let me know if u need further help.

Yes 100%.

View my post about TunnelBear. It’s 100% free VPN u use to change ur IP location. Try to tunnel to the US and then log into your account. If it doesn’t work the first time, disconnect and reconnect to the US tunnel and try logging in again. Then it will work.

VPNs are actually more secure than anything else. It hides your internet activity from the people hosting your WiFi, your WiFi company, and even the government in some cases. If u have any questions pls ask.

;sh=64074132

I would not use it since you have to give them your collegeboard username and password.

Instead use TunnelBear VPN. View my post below. Hope this helps!

;sh=ae8e5fc7

Download a vpn on your pc or phone- I use TunnelBear, although you can use any. It’ll reroute your privacy settings to appear as if your IP address is in a different location, and for most vpns, you can choose what that location is, which would be one of the states the ap scores are first released in

Easiest route is to use a secure site like where you just enter your username and password.

If you want to be extra secure, you can use a VPN. Install something like TunnelBear, select a US location (since TunnelBear servers are usually northeast US), then go to and fill in stuff.

Since CollegeBoard made it especially difficult for third-party sites to help verify your information, you're going to have to get a VPN to verify your account info. Try installing a VPN like TunnelBear, then connecting to a northeast US location.

After connecting to VPN, go to and try to login.

If that doesn't work, you will have to wait until your region's assigned day.

5s on Lit, Calc AB, U.S. gov and politics, euro, and human geography, a 4 on art history, and 2 on physics 1 lol (thought I'd make a 1 so I'm not upset at all, worst teacher in the universe) I used the TunnelBear app for iPhone

Last year, I had summer assignments for APUSH and Lit. For APUSH we had to read and take notes on the first chapter of the textbook, answer questions about that chapter, and fill out three different themed maps of the US (states/capitals, geographical features, and territory acquisitions). For Lit we read and annotated The Great Gatsby.

For the coming year I have to read Bird by Bird for Lang (the book is about writing advice) and pick out an interesting quote from each chapter. Our whole school is also reading another book on top of that, which the Lang classes also have to do a book review for. For AP Chem, it's a review of what we learned in first-year chem, like acids/bases, the periodic table, etc.

Seriously listen to /u/interrobangarangers, and good on you for sticking with it man. Considering the STEM prowess you've displayed already, I'm sure you'll be fine even if you have a bit less study time while doing summer reading. It's probably on your list, but I highly recommend On Writing Well by William Zinsser for AP Lang. If you ever have any AP Lang questions, feel free to PM me, I took the class last year and I enjoy helping people with it :) . Good luck.

For my class, we had to read The Jungle and The Elements of Style the summer going into the class. I feel like both books are really good on their own merits. The Jungle helps with understanding symbols in literature as well as realism as a writing style. The Elements of Style will definitely help with making your papers more elegant, which can especially help with the AP test.

A free Android mobile app I made that has easy access to resources (FRQs, scoring guidelines, exam formats, etc.) from the CollegeBoard website: https://play.google.com/store/apps/details?id=com.bglapps.kgusdorf.apguide

https://www.amazon.com/Advanced-Placement-World-History-Modern/dp/1531129161/ref=mp_s_a_1_1?crid=1CCMCXE3XZFQG&amp;keywords=amsco+world&amp;qid=1667241216&amp;qu=eyJxc2MiOiIwLjAwIiwicXNhIjoiMC4wMCIsInFzcCI6IjAuMDAifQ%3D%3D&amp;sprefix=amsco+world%...

Don't worry about it. I'm not sure how your school is but quarter grades don't actually ever get seen by colleges. (If that's what you are worried about anyways)

Here are some recommendations that I think will help you out this year:

1. TALK WITH YOUR TEACHER! If you need help, ask them! They are your best source, even if you may not like them all that much.
2. WATCH HEIMLER'S HISTORY on youtube! He is a life saver and gets you good info in easy to watch videos.
3. Don't sweat the specifics. I know from experience that having a general grasp on movements, time periods, etc will help you out more on MCQs than knowing super-specific information. Of course, specific info is good for some MCQs, SAQs, DBQs, and LEQs but for right now, I'd go with focusing on the general concepts. (Heimler will help you with this!)
4. Get the book 5 Steps to a 5. 100% will help you not only for studying for the actual AP test but also for the class in general! link to amazon assuming you take wh: modern

If this doesn't really help you feel free to say it! I'd be happy to help with any other questions you have.

There's actually a $20 textbook I'd recommend. Check this out. It was created and designed to focus only on the content in the AP curriculum and it goes through it in order. It's also better than some of those study books because those play under the assumption that you've already learned the ideas and you're just reviewing them. This textbook is teaching you, but keeping the scope more narrow.

As others have mentioned - Clifford and Khan are both great free options. If you want practice with questions, I'd recommend the 500 Questions book available. It's structured well and gives you a good idea as to what the questions look like

Took AP Chem this year, and if there's one thing I wish I could've done, it would be using Adrian Dingle's Crash Course book throughout the year instead of only in the last month.

I know 754 has already been done, but here is another alternative method to doing it:

As you probably know, the equation for a positive semicircle of radius R centered at the origin is sqrt(R²-x²).

Suppose that we have a rectangle of width 2x for which the midpoint of the bottom side is the origin (center of the circle). The area of that rectangle would be the width times height. The width has been established as being 2x, and the height must be sqrt(R²-x²). Therefore, the area is 2xsqrt(R²-x²)=sqrt2(R²x²-x⁴). Differentiate using the chain rule to get that the derivative of this area function wrt x is (2R²x-4x³)/sqrt(R²x²-x⁴). In order to find a maximum, solve for when this expression is equal to zero. For this to be true, the numerator must equal zero and the denominator cannot be zero: 2x(R²-2x²), which has solutions x=0 (makes the denominator zero, so this cannot be the thing that maximizes the function) and x=+/-sqrt(R²/2). We only need the positive case to get the answer by substitution: the area equals 2(sqrt(R²/2))*sqrt(R²-(R²/2)²)=2sqrt(R²/2)sqrt(R²/2), or R². So, the maximum area will be R².

This may be poorly explained, so here's a Desmos graph: https://www.desmos.com/calculator/yvycsbb8lb

AP CSP is actually one of the easiest APs ever lol. As long as you pay attention in class and do the work, you should be able to pass. The test involves some projects (but you have plenty of time to work on it, as it isn't timed or anything) and a MCQ, which is pretty straightforward and about basic coding techniques (and my class literally took a 30 minute nap during this MCQ lol and most of us got 5s).

Your class might use Scratch to help teach the basic coding principles, but it's pretty simple to learn. I can't think of any specific resources at the current moment though, but it also might help to learn about bases (like hex, binary, etc.) since there might be a few MCQs on it.

My school uses a different Physics for Scientists and Engineers that has a free downloadhere

Java: An Introduction to Problem Solving and Programming (4th Edition) by Walter Savitch.

Helped me a lot when I took the class. Is filled with a bunch of examples and detailed explanations.

Link: http://www.barnesandnoble.com/p/java-walter-savitch/1116754316/2671239606974?st=PLA&amp;sid=BNB_DRS_Marketplace+Shopping+Textbooks_00000000&amp;2sid=Google_&amp;sourceId=PLGoP20436&amp;k_clickid=3x20436&amp;kpid=2671239606974

mod 6 is arrays. I'm stuck on a challenge program that incorporates pretty much every concept that we've learned so far to make a program that separates hurricanes into categories from a text file. This program also requires you to separate the data into chunks based on user input, and I'm not really sure how to do that from a data file. I'm also stuck on this FRQ: https://hastebin.com/iraxigasun.sql -- I know how to find the min and max values, but I'm not sure how to create the array without the min and max values.

&#x200B;

&#x200B;

mod 7 is static methods. i;m a bit confused on incorporating the creation and reading of text files through static methods, along with the assignment prompt being a bit confusing as well.

&#x200B;

incorporating reading text files into more advanced topics seems to be one of my biggest problems

MOOC is "Massively Online ? Course". These are basically online courses. They can be useful in many circumstance. Advance prep in summer is one of the circumstances.

Udacity has an archived one (which means it's not live) https://www.udacity.com/course/intro-to-physics--ph100 You can watch the videos, answer a few questions and at least get an exposure to a number of topics. It's not quite the level of a real course, but you can consider it laying a 1" layer of a large number of base topics.

If you do this fairly quickly at the beginning of the summer, it will help you a lot. Then, if you have time-- and have gotten an equivalent base for all the other courses you are covering-- you can find another mooc that's a bit more deep.

Given the way 'self teaching' works, I'd suspect it's better to do the udacity level-- which specifically does NOT spend excess amounts of time on throwing in non-physics "complications" (like applying the physics in more complicated geometries etc.)-- and then moving on to the next level later.

Some students might think this is too "easy" and want to go to a class that is officially "Physics C" prep, but I'd say, get the base layer first. (It might be all you need. I say this as a person who only got "conceptual physics" before going to college. 'Cuz in the 70s. girls weren't supposed to go into engineering. But the base layer learned well... it helps more than all the weird complications.)

My class uses codingbat and Repl.it but my teacher also assigns us a bunch of projects and makes them all due by the day of the test. Tests have been pretty rough for the general class

There are options that will make your life easier. You'll be fine with what you have.

If you can't run BlueJ or VS Code, you'll have to stick to something online like repl.it -- repl.it will allow you to do all of what CSA requires of you. It won't do anything involving graphics. It's cloud based so you can store your files in your account and retrieve them later at home.

Otherwise, the other options are to just run java code through the command line using Notepad++ and javac.

The other suggestion that I can recommend is that you can attempt to wipe and install a *nix install on there (I suggest LXDE), that should let you install an IDE. But if you're at this point, you probably need a new laptop :)

I don't remember, so imma just say how this class stuff works.

When you refer to a variable via some superclass and use the subclass constructor, you instantiate the subclass, but you can only access superclass methods. The exception is polymorphism. Here's my demo. When you refer to a polymorphic method, Java uses the most specific method to the instantiated object, so the subclass method gets used. However, I think the x y z question was normal inheritance and access and whatnot.

You are placing the code they state is executed in the same method, so you didn't place the code in the correct spot. It's not in the same method:

The answer is correct.

AP (US?) Government: know your Constitution, know your Amendments, know your Supreme Court cases. Know your different types of interest groups, and your iron triangles; know the process of selective incorporation.

That's a decent chunk of the exam right there. This prep book does a great job of preparing for the exam. https://jet.com/product/detail/2376b515e40c4bb8a37a321fe7c47f99?jcmp=pla:ggl:media_a3:books_education_reference_a3_other:na:na:na:na:na:2&amp;code=PLA15&amp;k_clickid=cd72bfc6-f47e-46a6-b444-f1214d1acad8&amp;gclid=Cj0KEQiAnJqzBRCW0rGWnKnckOIBEiQA6...

the required textbook for me was brinkley but i usually read amsco instead and it's more clear. i would find a free pdf of it if you can (look on libgen.is) bc i don't think it's worth $25 but yeah you should at least try it.

also apushreview.com was a lifesaver for me, by the second semester i just watched the chapter review vids and filled out the note guides provided and did way better on class chapter quizzes than when i had taken notes on the whole chapter.

the website doesn't currently have videos for all of the give me liberty chapters but it has all of the brinkley chapters (somewhere on google it has a table of the chapters of all the textbooks and which ones line up) and you can also look at the general "apush videos in order" on the website for review.

i hope this all made sense, pm me if you have questions

Check if any of these will work for you: https://libgen.is/search.php?req=warriner&amp;open=0&amp;res=25&amp;view=simple&amp;phrase=1&amp;column=def

1) Thats way too vague

2) This is the wrong subreddit try r/textbookrequests or r/textbook_piracy

3) Always start with a search in library genesis (basic I tried)

I highly recommend taking mock exams or timed practice problems. You need to get comfortable with the time crunch. Do them over and over.

We finish the courses about a month or more before and take the rest of the time to practice. Often, we use free materials (YouTube, teacher websites, free problem sets) and still get those 4's and 5's. I can give you materials for certain course if you want.

For textbook-based classes, I recommend using outlines. I know it's a bit late now, but maybe next time. Writing the material down helps with recall, in my experience (I tried not doing it and it didn't go well).

If you're into flash cards, use Anki. It shows you cards based on how well you remember them. Total life saver. Quizlet is garbage in comparison.

&#x200B;

Then again... you could barely study, play too many video games, and still get those 5's. Your mileage will vary.

I'd recommend looking at Anki for some pointers.

I wanted to make something similar, but didn't have the free time to do so. The best feature is spaced-repetition, which is memorization on autopilot. As long as you write (or find) your flash cards early on and study them throughout the year, you WILL remember them because spaced-repetition will show your cards based on how much you've mastered them.

Anyway, just follow the UNIX philosophy.

For 23, I'll start with the basic formulas. You can set the force of gravity and centripetal force equations equal to each other since gravitational forces are centripetal in this case. Fg=(GM1M2)/r^2 = (mv^2)/r . Cancelling variables should leave you with v^2 = GM2/r . Using K = (1/2)M1v^2, solve for v^2 and plug plug it into that formula. Rearranging after that, you can get K=GM1M2/2r. From there, when r is 10 times, K has to be 1/10.

If you still don't get it, this power point shows it.

I know for a fact that this shouldn’t be normal. I had a teacher who taught Computer Science I (not ap) yet we were required to do the projects for the AP CSP exam (this was in 2020, so the exam portion was cancelled). She was very similar, barely did anything at all, we just watched videos and did random scratch projects and learned absolutely nothing. I worked very hard on my Create and Explore tasks and only got a 2 on the ”exam”. For APCSA, I’d recommend buying and studying back-to-front Barron’s AP Computer Science A I bought and self-studied APCSA entirely in the span of 3 months and got a 5 on the exam. If you want to get a good score on the exam, I’d highly recommend buying and utilizing this book. In terms of your teacher, I don’t have much advice other than asking directly to your teacher for content needed for the exam. If you aren’t already familiar with programming concepts, you NEED to be thought directly how different concepts work, otherwise the exam will likely be a struggle for you

I am totally in on that, one niche in the plan might be that I don't know if Hangouts will work with my computer (I'm running OpenBSD) and I'm wondering if there's any support in the Firefox application port for the Hangouts. Otherwise I'm game.

Side note:

I thought this was precalculus. I definitely remember doing these problems last year?

Also you guys haven’t done chain rule yet for derivatives?

We're not fully into Acids and Bases, so I can't help with the net ionic part, but I can help with the first portion.

It's HNO3 + NH3 --> NH4 + NO3, which makes NH4NO3. Ammonium Nitrate is the final product.

Acid-Bases always involve the exchange of a H+ ion from an acid to the base. You're adding a H+ ion from Nitric Acid, since it's an acid, to Ammonia, since it's a base. In this case, ammonia gained the H+ ion to make ammonium.

There's no need to balance because Ammonium (+1) and Nitrate (-1) share the "same" ionic charge to cancel out to 0 and everything is kept under control.

Now you should check out this link with an explanation for the net ionic part. Much better than what I can do.

NVM I got this completely wrong, look at https://socratic.org/questions/how-do-you-find-the-slope-of-the-polar-curve-r-cos-2theta-at-theta-pi-2 only do it for pi/6 rather than pi/2

Calc BC, Khanacademy is super helpful, but you can also check out brilliant.org

AP Spanish: when i took it, I had a friend who was a native Spanish speaker teach me a lot of it, but spanishdict was my best friend as well as lots of immersion (Spanish songs, movies, etc.)

APES: you should be fine for this one, I self studied the whole course in the 3 days before the test and got a 5

yes i've seen a couple of posts going around that are asking for a google classroom for self-studiers.

this is the first link i found & joined: https://classroom.google.com/u/1/c/MTQ5NTgwMzQ1MTUy

i thought it would be a good idea to have a central AP gc page where we post the google classroom links for the sub-AP google classrooms for each separate AP.

not for euro but for calc bc here's a presentation and notes for ab I didn't make them btw

https://classroom.google.com/u/0/c/Nzk2OTQ0NTg3MDBa

Check this out : https://tinychat.com/room/gottastudy (password : getstudying)

It's an amazing community with people all over the world and from different fields (medical, biology, computer science, law ...) the users either share their desktop screen or put camera on to avoid slacking while study periods. and eventually they can chat and help each other during breaks :)

In addition to using pomodoro technique (which I do with an online study buddy, the YouTube channel Study With Me), I use the Cold Turkey application, which lets me blacklist websites for a certain amount of time. It basically makes me so bored that studying/homework is the best thing that I can do. I have zero self control and this is the most effective way to stop procrastinating.

I just used this book (it was the only Stat book in my local bookstore, and also the one the class at my high school uses), read through it, did a lot of the problems along the way, then took a few practice tests before the real thing. Did it in March, took about two weeks, probably could've done it faster but I didn't want to burn myself out. I have a math background, though, so a lot of the probability stuff that my classmates struggled with was stuff I already kinda knew.

Precalc honors at my school is notoriously easy compared to the classes before and after it, so I can't really comment on that. I found Stat easier solely because I hate hyperbolas with a burning passion, but other than hyperbolas Precalc was easier for me personally.

I took Stat during the online year, so I had a ton of time and not enough homework to fill it, so time-wise I didn't have any problems. For a normal year I'd say it shouldn't be too bad, just start studying during winter break and you should be done well before the APs (and have time for harder stuff).

I used Barron’s AP Computer Science A Ninth Edition as my one and only resource. It was a really good book, and the practice tests definitely helped me. When I used this book, I went through a unit once a week and took notes over it.

I recommend The Smartypants' Guide to the AP Environmental Science Exam. I used this book only and got a 5. It is short and has all the info you need. I just highlighted, put tabs, & took notes on every single paragraph lol.

I quite liked Zumdahl's Chemistry textbook. AP 10th (https://www.amazon.com/Chemistry-Loose-Leaf-Version-Steven-Zumdahl/dp/1305957660/ref=tmm_other_meta_binding_swatch_0?_encoding=UTF8&amp;qid=&amp;sr=) This was the book I used for AP Chem in grade 10.

I used this YouTube channel (APESvsEverybody) lot last year and there’s a textbook we used in class but it’s kind of expensive (Environmental Science for the AP Course). APES is a relatively easy course so self-studying won’t be too difficult
