5 Steps to a 5: AP Physics C 2021 (TEST PREP) Paperback – 19 October 2020

I think this is perfect for self studying because Khan Academy is way too easy (and stupid repetitive) and other books are too challenging (or at least they cover every single possible thing, which makes it overwhelming).I wish I had used this book and did more drill on the problems I knew rather than always stressing on the other books and practice tests which contained mostly problems I didn't know. I'm sure I could've passed that way.The test was so easy. I only got a 3 because I felt I already had the basics down when I had last practiced them.Use memory recall and practice regularly. Good Luck

Overall everything was fine, but the advertising and front page of book claim "3 full-length practice exams", when in reality there are only two. It's the false advertising that earned it a low rating.
