Study Notes
MCAT Exam Overview
- MCAT is a program of the Association of American Medical Colleges
- The MCAT exam is structured into four sections:
- Biological and Biochemical Foundations of Living Systems
- Chemical and Physical Foundations of Biological Systems
- Psychological, Social, and Biological Foundations of Behavior
- Critical Analysis and Reasoning Skills
- The first three sections are organized around foundational concepts ("big ideas") in the sciences, emphasizing deep understanding of concepts over many facts.
- The MCAT exam tests scientific inquiry and reasoning skills, including knowledge of concepts and principles, scientific reasoning, problem-solving, reasoning about research design, and data-based reasoning.
- Critical Analysis and Reasoning Skills section tests analytical and reasoning skills needed for success in medical school.
- The MCAT exam covers a variety of topics, including scientific inquiry and reasoning skills, and the associated content categories from various disciplines.
