<p>What are some good books for the SAT II bio and SAT II U.S. History? I'm also taking the AP exams for both of them, but I've heard that the AP test and the SAT II test is completely different, so I was wondering if anybody could recommend me any good SAT II books.</p>
<p>Don't know for Bio, but for history they are similar. I read Princeton Review's book for both tests. </p>
<p>SAT II is more fact based & some more knitty gritty details, but they are generally the same.</p>
