<p>I'm taking an ap calc and is planning to buy a prep book to assist me for the ap test. Also, I'm taking regular physics and chemistry-- barely covers materials tested on ap. So I'm planning on self studying with a prep book for physics and chem. Which book is the best for independent study? I've tried Princeton review for bio and it was terrible. It didn't cover LOTS of materials on the actual test. Is barrons or he five step book any good??</p>
<p>I’m taking all 3 of these AP classes. I think PR is the best review book for all of them.</p>
