Familiarize yourself with the format of the biological sciences section. The section, which is last on the MCAT, consists of several brief passages followed by a related series of questions. There are also a number of standalone questions. You have 70 minutes to answer 52 questions.
Understand the level of knowledge necessary to succeed on the biological sciences section. Although some passages deal with advanced biological subject matter, you only need introductory-level knowledge of biology and organic chemistry to correctly answer the questions.
Study biology. Concentrate on basic molecular biology principles, cellular properties, genetics and evolution as they relate to vertebrates and microbes. Expand vertebrate studies to include the structure and interconnectedness of body systems and the physiological effects of external phenomena on organizing their form and function. More specifically, focus on viruses, enzymes, cell division and all body systems, including the nervous system, muscular system and lymphatic system.
Review organic chemistry material. Concepts covered on the MCAT include hydrolysis and dehydration, stereochemistry, amino acids, proteins, hydrocarbons, oxygen-containing compounds and laboratory techniques. You must also understand organic compound nomenclature, structure and classification, synthesis and retrosynthesis and reactions and reaction mechanisms.
Take a practice test under simulated testing conditions. Once you identify your problem areas, you can structure a studying system tailored to your specific needs. If you are unhappy with the score you receive on the practice MCAT, sign up for a prep course.
