MCAT (Medical College Admission Test) study guides
The MCAT is the standardized, multiple-choice exam required for admission to medical schools in the United States, Canada, and Australia.
Topics (10)
Biochemistry
25% of testAmino acids, enzyme kinetics, metabolic pathways, and molecular biology are the largest single content area on the MCAT, spanning both B/B and C/P sections.
Cell Biology & Genetics
10% of testCell biology, genetics, and evolution cover organelle function, DNA inheritance patterns, population genetics, and natural selection — tested in the MCAT B/B section.
General Chemistry
15% of testStoichiometry, thermodynamics, chemical equilibrium, acid-base chemistry, and electrochemistry are core MCAT C/P topics tested in quantitative passages.
Organic Chemistry
15% of testReaction mechanisms, stereochemistry, functional-group interconversion, and spectroscopy (IR, ¹H NMR, MS) are tested in MCAT C/P passages.
Physics
10% of testKinematics, mechanics, thermodynamics, optics, electrostatics, and circuits are tested in the MCAT C/P section with a biological and clinical context.
CARS — Critical Analysis and Reasoning Skills
25% of testCARS tests argument comprehension, inference, application, and rhetorical analysis using humanities and social-science passages — no outside knowledge is allowed or useful.
Psychology
10% of testSocial cognition, learning theory, memory models, sensation and perception, and biological bases of behavior are tested in the MCAT Psychological, Social, and Biological Foundations section.
Sociology
10% of testSocial stratification, health disparities, social institutions, cultural influences on behavior, and research methods are tested in the MCAT P/S section.
Research Methods & Statistics
10% of testExperimental design, control of variables, statistical reasoning, and scientific validity are cross-cutting skills tested throughout all four MCAT sections in passage-based questions.
Biochemistry Lab Techniques
5% of testGel electrophoresis, PCR, ELISA, centrifugation, chromatography, and spectrophotometry are high-yield MCAT techniques that appear as the experimental basis of B/B and C/P passages.
Locale-specific guides
Every MCAT topic is published with locale-specific framing for candidates testing in different countries. Pass-rate stats, regulatory context, and study tips all change by locale.
