<p>I got 740 Chem and 720 USH in June without much preparation. For USH, I'm planning to re-read AMSCO several times. For Chem....I have the Barrons SAT2 book and the Princeton AP book. Should I get the Barrons AP book as well? Any other suggestions?</p>
<p>In my opinion, the AP and SAT2 tests are very different. While they do test similar material, they're still different. I'd suggest getting SAT2 books. For Chem, I used Princeton Review. PR was really, really basic, and Barron's ... some of the stuff was too complicated. My friend used Kaplan, and he said it was extremely helpful. I think he got a 790 or 800.</p>
<p>I'd go with Kaplan.</p>
