We use these at work Ampad Computation Pad.
We also get regular loose leaf engineering paper. I like the notebook because the pages are quite large, so I can paste in full schematics (if I fold the page), or paste in pages of datasheets etc and it fits nicely.
Amazon has them!
Ampad Computation Book, 4x4 Quad Ruled, 76 Sheets, Ivory, 11-3/4" x 9-1/4", 1 per Pack (22-157) https://www.amazon.com/dp/B000DZEA2G/ref=cm_sw_r_cp_api_glt_fabc_TAZ74Y35AB5960S7FJAW
This one It’s the only one I’ve been able to find that’s spiral bound & I love it. I’m just about to buy a new one.
One of my favorite lab notebooks: https://www.amazon.com/Ampad-Computation-Ruled-Sheets-22-157/dp/B000DZEA2G/ref=sr_1_26?s=office-products&ie=UTF8&qid=1504571843&sr=1-26&keywords=ampad+gold+fibre
When I was in industry, they used these: https://www.eurekalabbook.com/products/green-quad-standard-lab-notebook
Here's how I study:
First I need an actual study place. I'm lucky to have an office. It's just a second bedroom but it's my own space. I spent a few bucks to spring for a comfy chair. I went to office max and sat in every display chair they had and compared prices and picked the one that was most comfortable that was within a reasonable price. Having the chair makes me feel more obligated to use that space instead of trying to do HW in front of the tv. Don't ever do homework in front of the TV if you need to learn what you are working on. Same goes for listening to music. Don't put on your favorite band. If you like playing music. Pick something without words. I personally like listening to chill beats when I'm studying. I'm not distracted but I don't feel uncomfortable either like I am in a hospital or something. Having a separate comfortable space really does matter a lot.
I am also super particular about what I write in. I don't have any lined paper. I have one notebook and it is a Spiralbound Ampad Gold Fibre Computation Book. It makes soooooooo much god damn difference. I normally would never be able to keep detailed notes like this because my handwriting is horrible and I'm too lazy to organize it. However having a nice notebook makes me want to keep nice notes. I know my notes aren't like a work of art but they are miles ahead of what they looked like last year.
You might also notice that I took those notes in pen. I only use pilot g2 black ink retractable pens. They are cheap, reliable, and writing with them is less physically exhausting then writing in pencil. A $12 pack of these pens is what I asked for at Christmas. Because it makes a real difference.
So I have my office, my chair, my notebook, my pens and it feels good to have those things that I all carefully picked out so it feels good to study and take notes.
My actual method of studying is to take notes in my office while I read the chapters. I don't take notes in class during the lecture. I don't know how anybody can listen and write and learn at the same time. So I use the Cornell method. Then I do all the homework off these notes. And when I take an exam I write the important formulas over and over for about 30 minutes before each test.
The older Ampad Engineers Research and Computation Book - Made in USA - were the best graph notebook available at any price. But they are now Made in Mexico, and are very far from good.
The TOPS Computation Book is not quite up to the older Ampad standard but it's very good. I am currently using these as work notebooks with fountain pen exclusively (fine nibs, Platinum Mix-Free inks at the moment but have used Noodlers, Mont Blanc Blue-Black, Pilot Iroshizuku with similar results).
They are expensive but I want to keep my notes basically forever. And when the paper is good enough to use both sides of each page with no bleed-through you get double the use.
