<p>I'm planning to take SAT II Biology, World History, and Math II soon. And I was wondering, which books do you guys recommend? I received a Kaplan SAT II study book for Biology and World History from a friend. But I heard from other people that Kaplan was worse in comparison to Barron's or PR. So I was wondering which books you guys prefer for each subject? Thanks in advance.</p>
<p>Math II - Barrons and Princeton Review. Use both.</p>
<p>My D really liked the Barron’s for AP World History, PR for APBIO. They worked well for SAT2s.</p>
