Q: What is the best brand of AP review books for the following subjects? For the following AP classes: AP US History, AP Biology, AP Psych
A: Barron is very dry, but covers almost every aspect of the topic (then again, no book has ever covered every topic). Tough read, but very good prep manual. Kaplan provides very good questions very similar to the real thing. If you're on a tight budget and can only buy one, I'd buy the kaplan books and have your teacher explain questions you don't get. S/he is paid a salary for a reason. But hell, if you can find a library that will let you loan the books out (most will only allow to use as reference only), that is best.
