Exam Content Breakdown

Based on the official Association of American Medical Colleges (AAMC) content outline

General Chemistry~30% (~18 questions)

Atomic structure, electron configuration, periodic trends, chemical bonding (ionic, covalent, metallic), stoichiometry, ideal and real gases, solutions and colligative properties, acids and bases (Brønsted–Lowry, pKa, buffers), chemical equilibrium (Kc, Kp, Le Chatelier's principle), thermodynamics (ΔH, ΔS, ΔG, Hess's law), kinetics (rate laws, Arrhenius equation, half-life), and electrochemistry (galvanic/electrolytic cells, Nernst equation, Faraday's laws).

Physics~25% (~15 questions)

Translational kinematics and dynamics (Newton's laws, forces, friction), energy and work (conservation of energy, power), momentum and collisions, fluids (Bernoulli's equation, continuity, hydrostatic pressure, surface tension, buoyancy), thermodynamics (heat, PV work, heat capacity), waves and sound (wavelength, frequency, Doppler effect, standing waves), electrostatics (Coulomb's law, electric fields and potential), circuits (Ohm's law, series/parallel resistors, capacitance), and light/optics (reflection, refraction, Snell's law, lens equation, wave optics). Atomic and nuclear physics: radioactive decay, half-life, photoelectric effect, de Broglie wavelength.

Organic Chemistry~15% (~9 questions)

Functional group identification and reactivity (alcohols, aldehydes, ketones, carboxylic acids, esters, amines, amides), stereochemistry (chirality, R/S, enantiomers, diastereomers, meso compounds), alkene and alkyne reactions (Markovnikov addition, electrophilic addition), substitution and elimination reactions (SN1, SN2, E1, E2), carbonyl chemistry, separations and purification (TLC, column chromatography, distillation, recrystallization), and spectroscopy (IR, ¹H NMR, mass spectrometry) as applied to biological molecules.

Introductory Biochemistry~25% (~15 questions)

Amino acid structure, ionization (pKa, isoelectric point, zwitterion), protein structure and function, enzyme kinetics (Michaelis–Menten, Km, Vmax, competitive/noncompetitive/uncompetitive inhibition, Lineweaver–Burk plots), lipid structure and biological membranes, metabolic processes framed through physical and chemical principles (acid–base physiology, bicarbonate buffer system, osmotic pressure in biological contexts).

Introductory Biology (contextual)~5% (~3 questions)

Biological systems contexts for physical/chemical principles: cardiovascular fluid dynamics, respiratory mechanics (surface tension, pulmonary surfactant), renal filtration (Starling equation), nerve conduction (membrane potential), and cellular chemistry — always tested through a physics or chemistry lens.

Why It's Free

Quality Exam Prep Shouldn't Cost Hundreds

I'm Ran Chen, an engineer with 20+ years of coding experience. I passed my Life Insurance license, EA exam, SIE, Series 6, 63, 65, and finally the CFP® exam.

Through all these exams, one thing became clear: exam prep is expensive. But with AI, we can change that. Quality preparation can now be free for everyone.
