    MCAT Sections: A Detailed Breakdown

    Pre-med students taking mcat exam

    As a pre-med student, you know the Medical College Admission Test (MCAT) is in your future. This standardized, multiple-choice exam is administered by the Association of American Medical Colleges (AAMC), and it’s a requirement for all aspiring doctors preparing to apply to medical school.

    Each year, more than 85,000 medical school hopefuls sit for the exam, so it’s important to prepare extensively and secure a good MCAT score. The most effective study plan includes closely reviewing the content that will be on the test.

    To gain a better understanding of what to expect, read on for a detailed breakdown of the MCAT sections.

    What’s on the MCAT? A section-by-section preview

    The MCAT is presented in a computer-based format, with 230 questions divided into four sections:

    1. Biological and Biochemical Foundations of Living Systems
    2. Chemical and Physical Foundations of Biological Systems
    3. Psychological, Social, and Biological Foundations of Behavior
    4. Critical Analysis and Reasoning Skills

    The first three sections are organized around foundational concepts in the sciences, while the final section focuses on an examinee’s comprehension abilities as they relate to the humanities and social sciences.

    Throughout the four sections of the MCAT, examinees are evaluated based on four foundational scientific inquiry and reasoning skills:

    1. Knowledge of scientific concepts and principles
    2. Scientific reasoning and problem-solving
    3. Reasoning about the design and execution of research
    4. Data-based and statistical reasoning
