What review books helped you get a 4 or 5?

<p>These kinda threads must have been made 1000x over, and this is my very first post, but whatever.</p>

<p>Last year, I took the AP US History exam and got a 5 because of a really great review book--the Kaplan AP US History Review Book. It was great because of the realistic questions (some of which I saw on the test) and in depth chapter reviews and essay question help.</p>

<p>On to my actual question: Would Kaplan be a good choice for AP Biology, AP Government, and AP Literature? What do you think is the best review book for getting a 5 on any of these exams? I really want to get a 5 on these next ones and I'd really like to rely on the RB. I'm gonna start studying this week, leaving me about 3 weeks of heavy study. REA seems too in-depth and I want something I can study in this amount of time.
Actually....w/e what are the best review books?</p>

<p>Thanks. :D</p>

<p>AP Bio - Cliff’s
AP U.S. Gov - Princeton Review</p>
