<p>I recently took the AP Biology exam and studied with the Barron's AP Bio review book. I'm going to take the SAT II Biology this Saturday, and I'm not sure if studying out of the AP book is going to be a good method. </p>
<p>I already took the AP Biology course and feel fairly confident about how i did on the AP exam, so I think all I need is a refresher. </p>
<p>Do the material in the two books differ greatly?</p>
