<p>I have the Princeton Review 2007 book for AP Chemistry and the Barrons 2007 book for SAT2 Chemistry. Should I study the Princeton book for AP Chem and I should be prepared for the SAT2 just by that? Or should I also study the Barrons?</p>
<p>Both will probably overprep you. If you have the time to study I would use the barrons.</p>
