Preparing for NEET 2025? With the short time and large syllabi to prepare, it is important to be smart about it. It is vital to focus on important chapters, or more aptly, the chapters with the most weightage, which have been asked in prior forms of the exam, and to also arrive at the important chapters based on marks allocated to them.
This may be something like Electrochemistry in Chemistry or Modern Physics in Physics. There will always be chapters that will be dominant in the question paper. This article will help you find out the important chapters in the fields of Physics, Chemistry, and Biology, and their expected number of questions based on trends created from prior question papers.
Subject | High-Weightage Topic | Avg. Questions | Marks (Approx.) | Key Concepts |
Physics | Modern Physics (Atoms, Nuclei, Semiconductors, Dual Nature) | 6-8 | 12-16 | Photoelectric effect, Radioactivity, Logic Gates |
Mechanics (Laws of Motion, Work-Energy, Rotational Motion) | 5-7 | 10-14 | Newton’s Laws, Moment of Inertia, Collisions | |
Electrodynamics (Electrostatics, Current Electricity, Magnetism) | 5-6 | 10-12 | Coulomb’s Law, Kirchhoff’s Laws, EMI | |
Optics (Ray & Wave Optics) | 4-5 | 8-10 | Lens Formula, Interference, Diffraction | |
Chemistry | Electrochemistry (Galvanic Cells, Nernst Eq., Conductivity) | 3-4 | 6-8 | Faraday’s Laws, Kohlrausch’s Law |
Organic Chemistry (GOC, Hydrocarbons, Alcohols) | 8-10 | 16-20 | IUPAC, Reaction Mechanisms, Named Reactions | |
Physical Chemistry (Thermodynamics, Chemical Kinetics) | 4-5 | 8-10 | Gibbs Free Energy, Rate Laws | |
Inorganic Chemistry (Chemical Bonding, p-Block, Coordination Compounds) | 6-8 | 12-16 | VSEPR Theory, Hybridization, Werner’s Theory | |
Biology | Human Physiology (Digestion, Respiration, Neural Control) | 12-15 | 24-30 | Nephron, ECG, Respiratory Volumes |
Genetics & Evolution (Mendelian Inheritance, DNA Replication) | 8-10 | 16-20 | Hardy-Weinberg Principle, Transcription | |
Plant Physiology (Photosynthesis, Respiration) | 6-8 | 12-16 | C3/C4 Pathways, Glycolysis, Kreb’s Cycle | |
Reproduction (Human Reproduction, Flowering Plants) | 6-7 | 12-14 | Menstrual Cycle, Pollination, Embryogenesis |
Important Information to Consider From The Table:
- Biology : highest weight (~90-100 questions), with Human Physiology having ~12-15 questions (24-30 marks).
- Physics: Modern Physics & Mechanics has ~12-15 questions (24-30 marks)—solving the numerical problems is important.
- Chemistry: Organic Chemistry is the most important (~8-10 questions) then Inorganic and Electrochemistry.
- Electrochemistry (3-4 Qs) and Modern Physics (6-8 Qs) bring the most marks, so be sure to master those topics.
Final Words for NEET 2025 Aspirants
