Quick answer
NTA does not publish chapter-wise weightage for NEET — all tables are reconstructed from past papers. The consistent pattern: in Biology, Human Physiology, Genetics and Evolution and Ecology carry the most questions; in Physics, Mechanics and Electrodynamics; in Chemistry, Organic basics, Coordination Compounds and Equilibrium. With 180 questions, even a one-question chapter is 4 marks, so weightage sets your revision order rather than telling you what to skip.
Biology (90 questions) #
| Unit | Typical questions |
|---|---|
| Human Physiology | 12–14 |
| Genetics and Evolution | 12–14 |
| Ecology and Environment | 9–11 |
| Plant Physiology | 8–10 |
| Cell Structure and Function | 8–10 |
| Reproduction | 8–10 |
| Diversity in Living World | 7–9 |
| Structural Organisation | 6–8 |
| Biotechnology | 5–7 |
| Biology and Human Welfare | 5–7 |
Physics (45 questions) #
| Area | Typical questions |
|---|---|
| Mechanics | 11–13 |
| Electrodynamics | 10–12 |
| Modern Physics | 5–6 |
| Optics | 4–5 |
| Heat and Thermodynamics | 4–5 |
| Oscillations and Waves | 3–4 |
| Electronic Devices | 2–3 |
Chemistry (45 questions) #
| Area | Typical questions |
|---|---|
| Organic (GOC + functional groups) | 12–15 |
| Inorganic (bonding, p-block, coordination) | 13–16 |
| Physical (equilibrium, thermo, kinetics, solutions) | 14–16 |
💡 Tips
- Ecology is the single best value unit in NEET — around 10 questions, largely factual, and one of the shortest units in the book.
- Modern Physics is the Physics equivalent: small, formula-driven, always present.
- High-weightage does not mean high-return. Genetics is heavy and hard; Ecology is heavy and easy. Start with the second kind.
- Weightage varies year to year. Anything above roughly 5 questions is reliably present; below that, treat presence as uncertain.
NEET chapter wise weightage — frequently asked questions
Does NTA release chapter wise weightage for NEET?
No. NTA publishes the syllabus but not chapter weightage. All weightage tables, including this one, are reconstructed from past-paper analysis.
Which chapters have the highest weightage in NEET?
In Biology, Human Physiology, Genetics and Evolution, and Ecology. In Physics, Mechanics and Electrodynamics. In Chemistry, organic functional groups, Coordination Compounds and Equilibrium.
Which NEET chapters give the best return for the effort?
Ecology in Biology and Modern Physics in Physics. Both are short, largely factual or formula-driven, and reliably worth several questions each year.
Can I skip low weightage chapters in NEET?
It is risky. Each question is 4 marks and the swing to a wrong answer is 5, so a skipped chapter that appears twice costs meaningfully. Study low-weight chapters to competence rather than dropping them.
Is NEET weightage the same every year?
Broadly stable for the major units but variable at the margins. Anything above roughly five questions is reliably present; below that, presence varies by paper.
