Stoichiometry and solutions
Dimensional analysis, dilutions, colligative properties, and concentration units used in passages.
MCAT chemistry lives mainly in Chemical and Physical Foundations, with biochemistry overlapping the living-systems section. The exam rewards setup: units, stoichiometry, acid-base reasoning, and the first two steps of an organic mechanism under time.
General chemistry on the MCAT is quantitative: gases, solutions, equilibrium, acids and bases, electrochemistry, and thermodynamics appear as word problems sitting on a short experiment. Organic chemistry is lighter than a full year-long course but still tests functional groups, stereochemistry, and high-yield reactions that change a spectroscopic or biological readout.
Physics shares the section. This page does not pretend to replace a physics plan. It keeps chemistry cards from swallowing the queue and leaves kinematics, circuits, and optics as a separate deck if you need one.
Dimensional analysis, dilutions, colligative properties, and concentration units used in passages.
Le Chatelier, Ka/Kb/pKa, buffers, and titration curves you can sketch from memory.
Nucleophiles, leaving groups, addition/elimination, and how IR/NMR hint at a product.
Enthalpy, Gibbs free energy, cells, and what a sign change means for spontaneity.
Built for someone who has taken gen chem and ochem but is rusty on timed setup. Physics review should sit in a parallel block, not inside these cards.
Weeks 1–4
Relearn unit conversions, equilibrium expressions, and acid-base identities until you can start a problem without rereading the formula sheet.
Weeks 5–8
Add organic reaction families and passage sets. Cards should ask for the next intermediate or the spectroscopic change, not a named-reaction trophy list.
Weeks 9–12
Take mixed section blocks. New cards come only from setup errors that repeat. Keep a formula sheet of last-mile identities, then retire it.
Chemistry cards fail when they store prose. A useful card starts the problem: “Write the expression for osmotic pressure,” “Which species is protonated at pH 2?”, “What peak disappears after oxidation?” You should be able to begin the math before you finish reading.
Spaced repetition keeps constants and functional-group behavior available while you spend live minutes on passages. The calculator prefill assumes a mid-size chemistry deck beside a physics deck, not one pile for the whole section.
Cover the solution and rebuild the first two lines, including units.
Hide the buffer region or equivalence point and name what is in the flask.
Ask only for the first elementary step. Save the full arrow-push for a weekly sketch.
350 chemistry cards at 35 minutes a day. Keep physics in a second deck so reviews stay specific.
Estimate: 30 seconds per new card, 10 seconds per review. Fixed review gaps, not FSRS or a recall prediction.
Your calculator inputs stay in this browser tab. No uploads, email or signup needed.
No. Focus on functional groups, stereochemistry, and reactions that change a spectrum or a biomolecule. A named-reaction encyclopedia is the wrong deck.
Keep a separate physics deck. Mixed reviews hide whether a miss was chemistry setup or a kinematics identity.
Identities you still derive slowly: Henderson–Hasselbalch, Nernst, Gibbs relations, and concentration conversions. Not every equation from the outline.
Upload a chapter or notes, generate editable cards, then delete any card that only restates a heading. Keep the ones that start a calculation or a mechanism.
