<p>I've heard, many times, that the best SAT II biology review book is the Cliff Notes AP book. And that the Princeton Review World History book is terrific.</p>
<p>Some say that the Kaplan Bio SAT II book has too many facts,
while the Princeton Review Bio has too few ... Yes?</p>
<p>If my question has been raised many times over -- I'm sorry! </p>
<p>Many thanks.</p>
