MCAT study guide

MCAT · Work through your exam, one topic at a time.

The Medical College Admission Test (MCAT) is the standardized exam that the AAMC administers for people preparing to apply to medical school. Per the AAMC, the exam "assesses your knowledge of natural and social sciences concepts and your critical thinking and scientific problem-solving skills required to begin the study of medicine." It is therefore a pre-matriculation readiness measure, not a licensure exam, and it is aimed at premed students who are building an application to medical school. Because the test blends science content with reasoning about experiments, data, and social-science passages, strong preparation combines content review with sustained practice in interpreting passages and evaluating evidence rather than memorization alone. The AAMC states that the exam is offered multiple times a year from January and March through September at hundreds of test sites in the United States, Canada, and around the world, and that roughly 95,000 people per year take it. Topics on this exam: Natural sciences concepts, Social sciences concepts, and Critical thinking and scientific problem-solving skills. The MCAT study guide has 3 sections and about 968 words.

01

Natural Sciences Concepts

This domain tests how well you apply biology, biochemistry, chemistry, and physics to living systems. Expect questions that combine a short experiment or physiological scenario with quantitative reasoning: enzyme kinetics, acid–base balance, thermodynamics, fluid flow, electrical circuits, and genetics.

02

Social Sciences Concepts

This domain tests psychology and sociology as empirical sciences. Questions ask you to identify concepts in scenarios, interpret research, and connect individual behavior to social structure: learning, memory, cognition, identity, stratification, institutions, and health disparities.

03

Critical Thinking and Scientific Problem-Solving Skills

This domain tests reasoning with passages and data rather than memorized facts. CARS asks you to identify arguments, assumptions, tone, and inferences; research-design questions ask you to evaluate variables, controls, validity, and causal claims.
