AP Preparation Books

<p>Hey Everyone, I'm new to this forum and looking for help.</p>

<p>I'll be taking the AP Exam for Biology, Chemistry, Physics B in May 2012. I need some expert replies on the preparatory books for the same :)</p>

<p>I already have access to some of the standard textbooks for the AP - so what I'm looking for in particular is material for review.</p>

<p>I will be going with Barron's for all three of the tests. In addition, I want one more review per test. For Bio, I liked CliffsNotes, Chem - Princeton Review and Physics - CliffsNotes. </p>

<p>What do you guys think? Are there any other books which might be better than what I have considered for the second set of books. Also, I am aware that Barron's books are more than adequate but I'm the sort of person who doesn't feel confident unless I am drastically over prepared. So, what do you guys think?? Pl. reply </p>

<p>Thank you very much in advance :) :) :)</p>
