MCAT Biological Sciences Section

What does the MCAT Biological Sciences section cover?

The MCAT Biological Sciences section can be broken into two generalized categories: organic chemistry and biological sciences. When taking this section of the MCAT, test takers are often presented with passages that provide highly specific details about complex biological functions. Questions then require test takers to integrate the provided specific information with generalized biology concepts to draw conclusions. Material in this section includes organic chemistry reactions and mechanisms, cell biology, molecular biology, evolution and genetics, systems biology, and some biochemistry.

How many problems are on the MCAT Biological Sciences section, and how much time do I have to complete them?

The MCAT Biological Sciences section consists of 52 questions. 70 minutes are allotted for this section. Approximately 40 to 45 questions will be based on passages, and the remaining questions will be stand-alone questions that do not have any background information provided.

Should I guess on the MCAT Biological Sciences section?

There is no guessing penalty on the MCAT. Scores are based on the number of questions answered correctly, and are not affected by questions skipped or answered incorrectly. It is a good strategy to answer every question on the exam, even if you must guess.

What kinds of problems are on the MCAT Biological Sciences section?

Questions in the MCAT Biological Sciences section can be passage-based or discrete. Discrete questions will generally be straightforward, asking for identification of biological terms and concepts or conclusions based on one to two sentences. Passage-based questions vary in content and structure. Some passages provide information about certain processes, while others provide experimental setups or data for analysis. Be prepared to identify new information that is provided in the passages and draw connections to your experiences with college coursework and material. Many questions will require application of general biological concepts to specific scenarios described in the passages.
