AP Art History, AP Biology, and AP World History test preparation?

For AP Art History, Barron's is the BEST by FAR. I'm using it right now to study and it simplifies everything yet is very informative. The format is great - it has pictures of the monuments/paintings with bullet points of the most important information. It has practice tests, summaries, and practice essay questions after every chapter. It's really helpful and if you study it well, you're pretty much guaranteed at least a 4. As for the other two, I can't say from personal experience, but of my friends who are taking it, most have the Princeton Review versions, which seem to have to most realistic tests and best chapters reviews. Good luck!!! :) Let's hope we both get 5's on everything :)

I haven't taken APbio but REA is great for history APs. I love using it because it guides you along and jogs your memory. It's essentially an outline so it is imperative that you actually have background knowledge about the topic but its great for a review!
