The NEET 2027 syllabus is your most important document before you begin preparation. It tells you exactly what NTA will test you on, which chapters to prioritise, and what has been removed so you do not waste time studying irrelevant content.
As of March 2026, NTA has not announced any syllabus changes for NEET 2027. The syllabus is expected to remain the same as NEET 2026, which follows the reduced NCERT curriculum introduced after the 2023 revision. This page will be updated immediately if NTA releases any official changes.
This guide gives you the complete chapter-wise syllabus for Biology, Physics, and Chemistry, the weightage breakdown for each subject, topics removed in the 2023 revision, and the high-priority chapters that appear most frequently in NEET papers.

NEET 2027 Syllabus: Biology
Biology carries 360 marks, which is 50% of the paper, making it the most important subject. The syllabus is split between Botany and Zoology, each carrying 180 marks. Nearly all questions come directly from NCERT.
Biology is where NEET is won or lost. Students who read NCERT Biology line by line, including every diagram, every table, and every footnote, have a decisive advantage over those who rely on summaries or note

NEET 2027 Syllabus: Physics
Physics carries 180 marks, which is 25% of the paper. NEET Physics is more about conceptual understanding and problem-solving rather than memorisation. It is often the subject where students lose the most marks, so strong preparation here is a differentiator.
Physics in NEET is different from JEE. Questions test application of concepts rather than mathematical derivation. Most Physics questions in NEET can be solved with a clear understanding of the concept and one correct formula. Lengthy calculations are rare.

Best Books for NEET 2027 Syllabus Preparation
Start with NCERT, always. For Biology, NCERT is 90% sufficient. For Physics and Chemistry, use NCERT for theory and add reference books for problem practice. Never start a reference book before completing the NCERT chapter.
| Subject | NCERT First | Reference Book |
|---|---|---|
| Biology | NCERT Class 11 and 12 | Trueman's Biology (Vol 1 and 2) |
| Chemistry | NCERT Class 11 and 12 | N Avasthi (Physical), MS Chauhan (Organic) |
| Physics | NCERT Class 11 and 12 | HC Verma or DC Pandey (MCQ) |
For PYQ practice, use the MTG 33 Year NEET Chapterwise book or Arihant NEET PYQ collections. Solving 10 years of previous year papers chapter-wise is the single most effective preparation activity after NCERT completion.

Conclusion
The NEET 2027 syllabus covers approximately 79 chapters across Biology, Physics, and Chemistry. Biology carries 360 marks at 50% of the paper, Physics and Chemistry carry 180 marks each at 25% a piece. Not all chapters carry equal weight. Focus on high-weightage chapters first and build outward.
Biology is non-negotiable. Master NCERT Biology completely before spending extra time on Physics and Chemistry reference books. The chapters that appear most in NEET, Genetics, Ecology, Human Physiology, Reproduction, Cell Biology, are all Biology chapters. Secure those 150 to 200 marks first, then build your Chemistry and Physics scores on top.
The official NEET 2027 syllabus PDF will be released by NTA along with the information brochure. Until then, the NEET 2026 syllabus is your most accurate reference.

FAQs
Is the NEET 2027 syllabus the same as NEET 2026?
As of March 2026, NTA has not announced any syllabus changes for NEET 2027. The syllabus is expected to remain the same as NEET 2026, which follows the reduced NCERT curriculum.. Students should follow the current official NTA syllabus and update their preparation if NTA announces changes with the 2027 information brochure.
How many chapters are there in the NEET 2027 syllabus?
The NTA NEET syllabus has a total of 79 chapters as per the latest NMC notified syllabus, covering all three subjects. Previously the syllabus had 97 chapters. The reduction happened in 2023 when NTA aligned the syllabus with the revised NCERT curriculum.
Is Class 11 Biology important for NEET 2027?
Yes, significantly. Class 11 Biology includes Cell Biology, Biomolecules, Plant Physiology, Human Physiology, Structural Organisation, and Diversity chapters, which together contribute approximately 40 to 45% of the Biology paper. Ignoring Class 11 Biology means losing nearly half the paper.
Is Communication Systems in NEET 2027 Physics syllabus?
No. Communication Systems was removed from the NEET Physics syllabus in the 2023 revision and remains removed. Do not include it in your preparation for NEET 2027.
Can I crack NEET 2027 with only NCERT?
For Biology, NCERT alone can fetch you 85 to 90% of Biology marks if read thoroughly. For Chemistry, NCERT covers Inorganic and Organic well, but Physical Chemistry may need supplementary numerical practice. For Physics, NCERT is essential for theory, but additional MCQ practice from reference books is needed. ALLEN In short, NCERT is necessary but not fully sufficient for Physics and Physical Chemistry.
Which subject has the highest weightage in NEET 2027?
Biology has the highest weightage at 360 marks out of 720, which is exactly 50% of the paper. It is split equally between Botany and Zoology at 180 marks each. Physics and Chemistry carry 180 marks each, making up 25% of the paper apiece.
