<p>I took AP Biology, World History, Psychology, Micro&Macroeconomics this year, and I'll be taking SAT2 Biology and World History next week. </p>

<p>Should I buy SAT2 Bio/WH books or should I just read over my AP prep books?</p>

<p>The AP books will probably be fine. In reality, if you felt confident about the AP Bio and APWH tests, you should be able to do well on the SAT II without studying at all.</p>
