๐Ÿ“š Subject-Wise Prep Guide

Biology, Chemistry, Physics, English, and Logical Reasoning don't reward the same kind of studying.

Most "subject-wise" guides just repeat the syllabus with a different header per subject. This one focuses on what actually changes between subjects โ€” how each one is best studied, and the specific mistake students repeatedly make in each.

What you won't find here: a precise MCQ-by-chapter breakdown within each subject. We checked, and even specialized prep sites disagree with each other on exact chapter-level weightage โ€” the kind of false-precision that's easy to publish and hard to verify. The subject-level weightage below is solid and verified. For the full official chapter list, see our MDCAT syllabus page.

Biology

Biology45% ยท 81 MCQs
Biomolecules & Enzymes Bioenergetics Cell Biology Biodiversity Coordination & Control Genetics Evolution Reproduction Body Systems Immunity
How to actually study it

Biology is dense but pattern-rich โ€” diagrams, cycles, and classification systems repeat across chapters once you notice the structure. Active recall (flashcards, self-testing) consistently beats re-reading, because Biology MCQs increasingly test whether you understand why a process happens, not just its name.

Mistake:Treating Biology as pure memorization. MDCAT scenario-based questions reward understanding mechanisms, not just recalling terms.

Chemistry

Chemistry25% ยท 45 MCQs
Atomic Structure Bonding Equilibrium Thermochemistry Reaction Kinetics Organic Chemistry Hydrocarbons Biochemistry
How to actually study it

Chemistry is really two subjects wearing one name. Physical chemistry (equilibrium, kinetics, thermochemistry) rewards understanding relationships between variables โ€” practice problems, not memorization. Organic chemistry rewards systematic pattern recognition across reaction types โ€” closer to Biology's style of studying than physical chemistry is.

Mistake:Avoiding organic chemistry because it feels memorization-heavy, then running out of time for it. It rewards early, steady practice far more than late cramming.

Physics

Physics20% ยท 36 MCQs
Vectors & Equilibrium Motion & Force Work & Energy Electrostatics Current Electricity Electromagnetism Atomic & Nuclear Physics
How to actually study it

Physics rewards applied practice over passive formula memorization. The same concept often gets rephrased in unfamiliar-looking questions, so the real skill is recognizing which formula applies to a new scenario โ€” which only comes from solving varied problems, not re-reading derivations.

Mistake:Memorizing formulas in isolation without practicing their application. Recognizing a formula and knowing when to use it are different skills.

English

English5% ยท 9 MCQs
Grammar Vocabulary Reading Comprehension
How to actually study it

Small section, but a high-efficiency one โ€” English MCQs are typically faster to answer correctly than a dense Biology or Chemistry question. Short, consistent daily practice (15-20 minutes of vocabulary and grammar) works better than cramming, since vocabulary genuinely benefits from spaced repetition over time.

Mistake:Ignoring English entirely because it's "only" 5%. Near-perfecting a small, fast section is one of the most efficient uses of late-stage prep time.

Logical Reasoning

Logical Reasoning5% ยท 9 MCQs
Pattern Recognition Logical Deduction Cause & Effect Course of Action
How to actually study it

There's no chapter to memorize here โ€” it's a skill section. The good news: many Logical Reasoning questions reuse similar structural templates, so regular exposure to varied practice sets genuinely improves performance, even without a textbook behind it.

Mistake:Assuming it can't be prepared for since "it's just IQ." Pattern familiarity helps more than people expect.

Frequently Asked Questions

Which MDCAT subject should I study the most?

Biology, since it's 45% of the paper โ€” more than Chemistry and Physics combined. But "most" doesn't mean "the same way" as the others.

Can Logical Reasoning actually be prepared for?

Yes โ€” despite feeling like pure aptitude, many questions reuse similar patterns, so regular practice genuinely helps.

Should I skip English since it's only 5%?

No โ€” it's fast, low-content, and one of the most efficient sections to near-perfect for the time it costs.
