SDN Members don't see this ad. (About Ads) Would the following classes be enough to get a perfect score in the biology portion of the biological sciences section? -Introduction to Cellular and Molecular Biology -Human Physiology -Molecular Biochemistry I I'll also obviously be going through a review book when the time for the MCAT approaches (I'm not taking it any time soon). I'm assuming the review book and maybe my old textbook from AP Biology would be sufficient to cover genetics and microbiology thoroughly enough for the MCAT. My friend got a 40 on the MCAT and, in addition to these courses, took a Molecular Biology course and a Genetics course, but I'm not sure those courses would actually be necessary or as important.
