SDN Members don't see this ad. (About Ads) I took AP Biology my junior year of highschool and tested out for college credit. I'm currently a sophomore and plan on taking the MCAT this up coming august. I'll have cell biology and genetics under by belt before I take it as far as biology goes, but what is the best way to review all of the other topics? I honestly do not remember much at all from the class. Is it to simply just review a general biology textbook or use a different review book? I'm taking a Princeton review course over the summer. Thanks!
