NEET Syllabus 2026: Physics, Chemistry & Biology Topics

The NEET syllabus is the fixed set of Physics, Chemistry, and Biology topics from the Class 11 and 12 NCERT curriculum that the National Testing Agency (NTA) tests every NEET UG candidate on. For 2026, the National Medical Commission (NMC) has confirmed no change from the reduced 79-chapter syllabus introduced in 2024, so students preparing for NEET UG 2026 can rely on the same unit-wise topic list used last year. This guide breaks down that syllabus subject by subject, with chapter weightage, so you can prioritize your study time.

Key Takeaways

• The NEET syllabus 2026 is unchanged from 2025: 79 chapters total across Physics, Chemistry, and Biology, drawn from NCERT Class 11-12 textbooks.

• Biology carries the highest weightage at roughly 50% of the 720-mark paper, with Physics and Chemistry at about 25% each.

• Within Biology, Human Physiology (35-40%) and Genetics & Evolution (18-20%) are the highest-weightage chapters; in Chemistry, Organic Chemistry carries the largest share (30-35%).

• NEET UG 2026 was held on 21 June 2026, with results declared 16 July 2026; around 11.21 lakh of the 20.97 lakh candidates who appeared qualified, per NTA data.

• The official syllabus PDF is published by NTA and NMC; always cross-check the current-year document rather than relying on a cached copy from a previous cycle.

What Subjects Does the NEET Syllabus Cover?

The NEET syllabus 2026 spans three subjects — Physics, Chemistry, and Biology — with Biology split into Botany and Zoology for exam-paper purposes, even though both draw from the same unified Biology syllabus. All topics are drawn from the NCERT Class 11 and Class 12 textbooks, which is why NCERT mastery, not supplementary reference books, remains the foundation of NEET preparation.

What Is the NEET Biology Syllabus?

Biology is the highest-scoring section of NEET, worth 360 of the paper's 720 marks, and is divided into ten broad units: Diversity in Living World, Structural Organisation in Animals and Plants, Cell Structure and Function, Plant Physiology, Human Physiology, Reproduction, Genetics and Evolution, Biology and Human Welfare, Biotechnology and Its Applications, and Ecology and Environment. Human Physiology alone accounts for roughly 35-40% of Biology's weightage, making it the single highest-priority chapter group in the entire syllabus, followed by Genetics and Evolution at 18-20%.

What Is the NEET Physics Syllabus?

The Physics syllabus covers 20 units from Physics and Measurement through Experimental Skills, including Kinematics, Laws of Motion, Thermodynamics, Electrostatics, Current Electricity, Magnetic Effects of Current, Optics, and Atoms and Nuclei. Mechanics-related chapters (Laws of Motion, Work Energy and Power, Rotational Motion) together carry the largest share of Physics weightage at roughly 25-30%, with current electricity and magnetism close behind at 20-22%.

What Is the NEET Chemistry Syllabus?

Chemistry is split into three sections: Physical Chemistry (8 units, including Chemical Thermodynamics, Solutions, and Chemical Kinetics), Inorganic Chemistry (4 units, including Periodicity and Coordination Compounds), and Organic Chemistry (8 units, including Hydrocarbons, Biomolecules, and Organic Compounds Containing Nitrogen). Organic Chemistry carries the highest weightage within the subject at roughly 30-35%, followed closely by Physical Chemistry topics like chemical bonding and thermodynamics.

Has the NEET Syllabus Changed for 2026?

No. NMC has confirmed there is no change to the NEET UG syllabus for 2026 compared to 2025. The last major revision took place in 2024, when NMC streamlined the syllabus from 97 chapters down to 79 by removing lower-yield topics across all three subjects — a change intended to reduce rote-memorization load without cutting core concepts. Since NMC periodically revises syllabus scope and chapter weightage between cycles, always confirm the current-year document directly from NTA before finalizing your study plan.

How Should You Use Chapter Weightage While Studying?

Chapter weightage tells you where to spend limited revision time, not which chapters to skip entirely, since NEET's negative marking (−1 for each wrong answer) punishes guesswork on any topic, high- or low-weightage. A practical approach for working through the syllabus:

1. Master the highest-weightage chapters first — Human Physiology, Genetics and Evolution, Organic Chemistry, and Mechanics.

2. Cover every remaining chapter at least once, in order of approximate marks-per-chapter.

3. Solve NCERT-based previous year questions (PYQs) for each unit as you finish it, rather than saving all PYQ practice for the end.

4. Reserve your final revision weeks for full-length mock tests covering the entire syllabus, not just high-weightage chapters.

This syllabus is also the foundation NEET UG relies on for MBBS, BDS, and other undergraduate medical admissions, so full coverage — not just high-weightage chapters — matters for your final score.
