<p>Hi, Iam a high school sophomore taking AP Bio. I want to take SAT-II: Biology E/M in Hune of 2011, after finishing AP Bio. exam in May. I like to purchase two prep books of SAT-II: Biology. I am thinking of purchase Princeton Review and Barron's, but is this combination good or do you recommend other SAT-II: Biology E/M prep books?</p>
<p>Use your AP book (cliffs)</p>
<p>^I agree. AP classes are generally more extensive than subject tests, so you should be fine with Cliffs, or the book you use to prepare for the AP exam.</p>
<p>It’s general consensus on here that Princeton Review & Barron’s are the best combination of books to use when studying for bio. PR is thorough and has good diagrams, while Barron’s should be used more as a review.</p>
