The official AAMC MCAT syllabus is structured around 10 Foundational Concepts spanning natural, physical, and social sciences. Knowing the exact topic distribution prevents you from wasting time on low-yield concepts.
Rather than organizing the syllabus purely by college course titles, the AAMC tests interdisciplinary science. For example, a single passage might combine enzyme kinetics with physics fluid dynamics and cellular transport mechanisms.
Subject-Wise Weightage Breakdown
| Subject Domain | Approximate Exam Weightage | Key High-Yield Topics |
|---|---|---|
| Biochemistry | 25% | Enzyme Kinetics, Metabolic Pathways (Glycolysis, Krebs, ETC), Amino Acids & Proteins |
| Biology | 65% of BBSB / 5% of CPBS | Cellular Biology, Molecular Genetics, Organ Systems, Physiology |
| General Chemistry | 30% of CPBS | Thermodynamics, Kinetics, Chemical Equilibrium, Electrochemistry, Acids & Bases |
| Organic Chemistry | 15% of CPBS | Separation Techniques, Spectroscopy (NMR/IR), Functional Groups, Reactions |
| Physics | 25% of CPBS | Fluids, Work/Energy, Waves/Sound, Electrostatics, Optics |
| Psychology & Sociology | 100% of PSBB | Cognition, Memory, Social Stratification, Identity, Perception, Learning Theory |
The 10 AAMC Foundational Concepts Explained
- Concept 1: Biomolecules & Molecular Assembly (Proteins, Lipids, Nucleic Acids)
- Concept 2: Cellular Structure & Division (Eukaryotes, Prokaryotes, Viruses, Mitosis/Meiosis)
- Concept 3: Organ Systems & Homeostasis (Nervous, Endocrine, Circulatory, Renal, Immune Systems)
- Concept 4: Physical Principles of Biological Systems (Fluids, Electricity, Optics, Thermodynamics)
- Concept 5: Chemical Principles & Reactions (Acids/Bases, Reaction Kinetics, Solutions)
- Concept 6: Psychological Processes & Cognition (Sensation, Perception, Memory, Attention)
- Concept 7: Biological Basis of Behavior & Emotion (Brain Structures, Neurotransmitters)
- Concept 8: Social Structure & Cultural Processes (Social Institutions, Inequality, Demographics)
- Concept 9: Self-Identity & Social Interaction (Group Dynamics, Stereotypes, Socialization)
- Concept 10: Critical Analysis in Humanities & Social Sciences (CARS Passages & Logic)
“EduQuest recommends organizing syllabus review around AAMC Foundational Concepts rather than textbook chapter numbers.”
Strategic Advice for Syllabus Coverage
Biochemistry and Psychology/Sociology account for nearly 50% of the non-CARS test content. Prioritize these two subjects early in your schedule. EduQuest provides specialized topic-wise study modules covering every AAMC concept.

Has the MCAT syllabus changed for 2026?
The AAMC Foundational Concepts remain consistent, with continued high emphasis on Biochemistry and Psychology/Sociology data interpretation.
Do I need calculus for the MCAT physics syllabus?
No, MCAT physics is algebra-based. You need strong scientific notation skills, unit conversions, and trigonometry fundamentals.
