<p>I'm starting to gather up prep materials for next year's AP classes, and have everything sorted out except for Calc AB. From what I have seen, the general consensus on the board is that both Princeton Review and Peterson's books do a good job of reflecting what is going to be on the test.</p>
<p>I also plan on getting Barron's Calc book, since it contains a lot of practice tests and I strongly believe that the overprep Barron's generally provides is invaluable. Which one of the other books would supplement Barron's the best: Princeton Review or Peterson's?</p>
