Exam prep · MCAT

MCAT flashcards for all four sections

The MCAT tests reasoning on top of a very large base of facts. The base is where flashcards earn their keep: amino acids, enzyme kinetics, hormone pathways, psych terms. Start with the decks below, then card your own content review books so nothing slips.

What the MCAT tests

  • Biology and biochemistry. Cells, genetics, metabolism, enzymes, amino acids, the major organ systems. The largest share of science content. Study guide →
  • General chemistry. Stoichiometry, thermodynamics, kinetics, equilibrium, acids and bases, electrochemistry. Study guide →
  • Organic chemistry. Functional groups, reactions, stereochemistry, separations and spectroscopy. Study guide →
  • Physics. Mechanics, fluids, circuits, waves and optics, with equations you must recall without a sheet. Study guide →
  • Psychology and sociology. Perception, learning, memory, personality, social structures and demographics. Heavily term-based. Study guide →
  • CARS. Critical analysis and reasoning on humanities and social-science passages. No outside knowledge needed; practice, not cards. Study guide →

MCAT unit study guides

Each guide is the unit on one page: a mindmap, the ideas in order, a worked exam-style question, the mistake students make most, then the flashcards and quiz for it.

Sample cards from “Biology: Cell Structure and Function”

What is osmosis?

Answer: The diffusion of water across a selectively permeable membrane.

Explanation

Water moves toward the side with more solute (less free water).

How does meiosis differ from mitosis?

Answer: Meiosis has two divisions and produces four genetically different haploid cells (gametes); mitosis produces two identical diploid cells.

Explanation

Crossing over in prophase I creates genetic variation.

What is the end result of mitosis?

Answer: Two genetically identical diploid daughter cells.

Explanation

Used for growth and repair.

List the stages of mitosis in order.

Answer: Prophase, metaphase, anaphase, telophase (PMAT).

Explanation

Followed by cytokinesis, which divides the cytoplasm.

What are the phases of the cell cycle?

Answer: Interphase (G1, S, G2), then M phase (mitosis and cytokinesis).

Explanation

DNA is replicated during S phase.

What is fermentation?

Answer: An anaerobic process that regenerates NAD+ so glycolysis can continue, producing lactic acid or ethanol and CO2.

Explanation

Yields only the 2 ATP from glycolysis.

A flashcard study plan for the MCAT

  1. Month 1: content review by section. Each study day, read a chapter, then upload it and generate a deck. Study the generated deck the next morning before new material.
  2. Month 2: full-length practice every other week. Card every missed science question. Daily CARS passages; no cards, just timing.
  3. Month 3: taper new content. Study only the missed deck plus high-yield decks (amino acids, hormones, physics equations, psych terms).
  4. Last week: two light review days, one rest day, no full-lengths in the final 72 hours.

How to write MCAT cards that work

  • Amino acids deserve their own deck: structure, one-letter code, charge at physiological pH, polar or nonpolar.
  • Physics equation cards should include the units and the situation they apply to, not just the symbols.
  • Psych and soc terms are pure recall and pure points. Card every bolded term in your review book.
  • Keep figures on the cards. Pathway diagrams and graphs cropped from your PDF beat retyped text for biochemistry.

Questions

Are these decks a replacement for a full MCAT deck?

No. They cover the foundations. The highest-yield cards are the ones you make from your own content review and practice-test misses.

Can I use Quizcard with Anki?

Yes. Generate decks here from your PDFs and export to CSV; Anki imports it. Many people do both.

How many documents can I generate?

Two free, fifteen a month on Plus ($6.99) and forty a month on Pro ($12.99), which also reads longer documents (up to 150 pages).
