I’ll add my 2 cents: this may help, get the book “humongous book of calculus problems by Michael Kelly” (see link below).
You may brush up on the fundamental theorem/topics of your choice to prepare you for Calc 3 multivariable calculus.
This book got me through 124/125. It didn't follow in the exact order of the concepts in class, but doing these practice exercises over and over I was way more prepared for tests than just doing the homework. https://www.amazon.com/Humongous-Book-Calculus-Problems-Books/dp/1592575129/ref=sr_1_4
I found The Humongous Book of Calculus Problems to be very helpful. It breaks down a lot of the concepts simply and also gives you problems to work. It helped me refresh Calc I before Calc II and helped me prepare for Calc II ahead of time.
With Calc II trig identities come up a lot. Memorize them all. It would also be a good idea to know the unit circle very well. A flashcard program like anki can be very good for all the memorization this course requires.
In another thread someone recommended the humongous book of calculus problems. I couldn't find a copy at a library though. Maybe I should just sack up and actually pay for it D:
My apologizes. I was under the impression that you were going to jump into calculus without the basic foundations under your belt. Here is the deal with mathematics in general. Like nursing or medicine you need to continue to practice you skills, study your skills and exercise your skills regularly. I still buy practice books of calculus problems and run through them.
This is a great book

Khan Academy is cool if you want to self teach on your own. It can take you far, however, taking tests under pressure to prove that you have retained the materials is most recommended.
Great resources are Mathantics and Professor Leonard on YouTube.
Again, sorry I came across that way. I just want to be honest. Calculus is not a joke and Calc 2 and 3 are more difficult concepts. If you think you can get away with it, do it. It is not for everybody. I also recommend using the library tutor system if you get stuck. Good luck.
