Which AP Study Books to Get?

<p>This year I’ll be a sophomore taking AP US History and AP Biology. I was wondering which brand of books (Princeton Review, Barron’s, any others) would be best to get as a study aide. I want something that will help me review for the AP Test and for the class tests.</p>

<p>Also, would AP Study Books be sufficient for SAT 2’s, or should I get a separate book to study for those? (I’ll be taking the AP and SAT 2 tests for both subjects in the spring of 2011.)</p>
