Typical topic weights across recent papers, subject by subject. Use them to decide what to revise first — never to decide what to skip.
Weights below are typical patterns across recent papers, not guarantees. Use them to decide what to revise first, never to skip anything.
| Topic block | Typical share | Why it matters |
|---|---|---|
| Mechanics (kinematics, laws of motion, work-energy, rotation, gravitation) | About 25–30% | The largest block and the foundation of everything else. Rotation is the single most commonly avoided topic and one of the most rewarding. |
| Electrodynamics (electrostatics, current, magnetism, EMI, AC) | About 25–30% | Equal to mechanics in most JEE papers. Electrostatics and capacitors are dense with formulae; current electricity is the most reliable scoring chapter in the subject. |
| Modern physics (atoms, nuclei, photoelectric effect, semiconductors) | About 12–18% | Small syllabus, consistently high return. In NEET this is the best marks-per-hour in the paper. |
| Optics and waves | About 12–15% | Ray optics is formula-driven and dependable; wave optics is less so. |
| Thermodynamics and kinetic theory | About 8–12% | Overlaps heavily with Physical Chemistry — study them together and the work halves. |
| SHM, waves on strings, sound | About 6–10% | Mathematically tidy and worth securing early. |
Chemistry is three subjects wearing one name, and they demand three different kinds of work.
| Topic block | Typical share | Why it matters |
|---|---|---|
| Physical Chemistry (mole concept, equilibrium, thermodynamics, electrochemistry, kinetics, solutions) | About 35% | Numerical and learnable. The mole concept underlies the whole subject — a weakness there shows up in every other chapter. |
| Organic Chemistry (GOC, hydrocarbons, functional groups, biomolecules, polymers) | About 35% | The part students fear and the part that rewards understanding most. General Organic Chemistry — inductive effects, resonance, hyperconjugation, stability — is not a chapter, it is the grammar of everything that follows. Learn it once, properly. |
| Inorganic Chemistry (periodic table, chemical bonding, coordination compounds, p-block, d-block, metallurgy) | About 30% | Largely memory, and almost entirely inside NCERT. Coordination compounds and chemical bonding are the two chapters that repay actual understanding. |
| For NEET specifically | — | Inorganic and Organic are drawn very directly from NCERT lines. Reading the textbook properly is worth more than any reference book. |
Mathematics has no shortcut. The only reliable method is to solve a very large number of problems and to be honest about which ones you could not do.
| Topic block | Typical share | Why it matters |
|---|---|---|
| Calculus (limits, continuity, differentiation, application of derivatives, integration, differential equations) | About 30–35% | The largest single block. Definite integration and area under curves recur every year. |
| Algebra (quadratics, sequences, binomial, matrices, determinants, complex numbers, permutations and combinations, probability) | About 30% | Matrices and determinants are the most dependable marks in the paper. Probability and P&C are where careless candidates lose most. |
| Coordinate geometry (straight lines, circles, parabola, ellipse, hyperbola) | About 15–20% | Formula-heavy and very scoring once the standard results are automatic. |
| Trigonometry and its inverse functions | About 8–10% | Small on its own, but trigonometric identities appear inside calculus questions constantly. |
| Vectors and 3D geometry | About 8–12% | Short syllabus, high return, and usually two guaranteed questions. |
Ninety questions, 360 marks — half the paper. The NCERT textbooks for Classes 11 and 12 are the syllabus, not a suggestion.
| Topic block | Typical share | Why it matters |
|---|---|---|
| Human physiology | About 20% | The heaviest chapter block in Class 11. Digestion, circulation, excretion, neural and chemical coordination. |
| Genetics and evolution | About 18% | Molecular basis of inheritance is the single most productive chapter in the whole paper. |
| Cell structure and function, and cell cycle | About 12% | Short, diagram-heavy, and consistently examined. |
| Plant physiology | About 10% | Photosynthesis and respiration, usually with numerical detail. |
| Ecology and environment | About 10–12% | The easiest marks in the paper — a small, factual, self-contained block that many candidates leave until it is too late. |
| Biotechnology and its applications | About 8% | Modern, factual, and drawn straight from NCERT. |
| Diversity of living organisms, structural organisation, reproduction | About 20% | Classification detail that must be memorised; the diagrams and their captions are examined directly. |
Exam patterns, syllabuses and eligibility rules change almost every year. Everything here is described as it stood in the 2025 cycle and is meant to orient you, not to replace the official information bulletin — read that document yourself before you plan anything, and check the official websites for dates.
