Biological and Biochemical Foundations Section
The formal name of this section is Biological and Biochemical Foundations of Living Systems, but since that’s a mouthful, let’s call it Bio/Biochem. The MCAT contains integrated sections which means that the subjects are not tested independently, but include overlapping areas of concentration, more closely reflecting the way you’ll encounter these subjects in medical school.
While the Bio/Biochem section may superficially appear to be a section that’s testing the “biological sciences,” it’s actually far more complex. While biology and biochemistry will comprise the majority of the Bio/Biochem section on the MCAT, there will also be some organic chemistry and general chemistry tested in this section, as they provide a background to the biochemistry.
As a first step, you should plan on completing a sequence in general biology and upper division biochemistry. The section is 95 minutes in length, with 59 questions, 15 of which are standalone, non-passage-related, discrete questions. The rest of the section contains passages which have questions which rely on both information from the passage and outside content knowledge to solve.
