Preparing for the MCAT

The biology and biochemistry the exam leans on, in a sensible order, with original MCAT-style questions at the end of every lesson and a review queue that brings back what you missed.

  1. 30 lessons

    Biochemistry

    Biochemistry runs through both science sections that test biology.

    Start: Vitalism: How Chemistry Captured Life →

  2. 26 lessons

    Cell Biology

    Cells, membranes, transport and signaling, which sit under most passages.

    Start: A Measured Eukaryotic Cell →

  3. 26 lessons

    Genetics and Molecular Biology

    Inheritance, gene expression and the experiments that show how we know.

    Start: Mendel's Peas: Segregation and Independent Assortment →

  4. 26 lessons

    Organismal Biology

    How whole organisms work: organ systems, physiology and homeostasis.

    Start: What an Organism Has to Do →

  5. 28 lessons

    Neuroscience

    Neurons, synapses and systems, for the biology and the psychology sections.

    Start: The Map: How the Nervous System Is Organized →

  6. Optional · 30 lessons

    Sensory Systems

    Sensation and perception in depth, a topic the psychology section tests.

    Start: Five Ways to Turn a Stimulus into a Current →

The exam also tests general and organic chemistry, physics, psychology and sociology, and critical reading (CARS). Those courses are not built here yet.

The official practice materials and the fee assistance program come from the exam’s maker, the AAMC. AAMC: prepare for the MCAT exam · AAMC Fee Assistance Program
