Best Prep Book for AP Physics 1

Hi, I am in AP Physics 1. I am planning on taking the AP Test for this class. Which is the best prep book?

If you want a review of the subject, 5 steps to a 5 is good. If your teacher doesn’t teach anything though, I would recommend Princeton Review. PR has a bunch of unnecessary information, but it does the job well (I got a 5 last year from using the book). Hopefully this helps!

AP Physics 1 Essentials is very useful and outlines what is and what isn’t going to be on the exam. http://aplusphysics.com/ap1/

Princeton’s is pretty good. For more help learning course material, EdX and Bozeman Science do a good job.
