The NEET UG syllabus is the single most important document in your medical entrance preparation. It defines exactly what NTA expects you to know, separates in-scope topics from wasted study time, and forms the basis for every preparation decision: which chapters to prioritise, which books to use, and which previous year questions to solve first.
This page provides the complete NEET UG 2027 syllabus as prescribed by the National Medical Commission (NMC) through the Undergraduate Medical Education Board (UGMEB), with chapter-wise topic lists for Biology (Botany and Zoology), Chemistry, and Physics, weightage analysis based on 10 years of NEET paper data, and a preparation strategy for each subject.
The NMC officially updated the NEET UG syllabus on December 17, 2024. This revised syllabus applies to NEET UG 2025 and 2026 and is expected to remain unchanged for 2027. The total syllabus covers 79 chapters across all three subjects.
Official Source: The NEET UG syllabus is published by the NMC and NTA in the official Information Bulletin at neet.nta.nic.in. The syllabus described here is based on the NMC-notified 2025 revision. Verify against the official 2027 bulletin when released.

The NMC officially updated the NEET UG syllabus on December 17, 2024. Some topics were removed or reduced in scope. Candidates preparing for NEET 2027 must not invest time in these removed areas.
| Subject Removed or Significantly Reduced Topics | |
| Physics | Communication Systems (fully removed from Class 12 NCERT) |
| Chemistry | Environmental Chemistry (significantly reduced; basic concepts retained) |
| Biology | Several sub-topics from Biomolecules (full chapter reduced in scope as per updated NCERT) |
The safest approach is to follow the official NMC-notified syllabus PDF from the NTA Information Bulletin rather than relying on older syllabus lists. The chapter structure above reflects the current NMC 2024 revision that applies through NEET 2026 and is expected to continue for 2027.
Download the official NMC syllabus PDF from neet.nta.nic.in once the 2027 bulletin is released. Until then, use the current NMC-notified syllabus (December 2024 version). Print it and stick it at your study desk.
Before opening any reference book, confirm that the chapter exists in the current NEET syllabus. Avoid wasting time on NCERT chapters that have been excluded from the NEET scope.
Use the weightage tables above to rank chapters by importance. Very High and High weightage chapters together account for 70 to 80 percent of the NEET paper. Cover them first, cover them deeply, and test yourself on them first before moving to Moderate and lower-weightage chapters.
Our interactive syllabus tracker lets you mark each chapter as Not Started, In Progress, or Completed across all three subjects. It shows your overall coverage percentage, flags neglected chapters, and helps you plan your remaining timeline realistically.

After completing each chapter, immediately solve all PYQs from that chapter available in our chapter-wise PYQ sets:
| Subject Book Title Author Purpose | |||
| Biology | NCERT Biology Class 11 and 12 | NCERT | Primary resource; non-negotiable |
| Biology | Trueman's Elementary Biology Vol 1 and 2 | K.N. Bhatia, M.P. Tyagi | Conceptual clarity and diagrams |
| Biology | Objective Biology | Dinesh | MCQ practice |
| Chemistry | NCERT Chemistry Class 11 and 12 | NCERT | Primary resource for all branches |

| Chemistry | Organic Chemistry | MS Chauhan | Mechanism-based Organic practice |
| Chemistry | VK Jaiswal Inorganic Chemistry | VK Jaiswal | Inorganic pattern practice |
| Physics | NCERT Physics Class 11 and 12 | NCERT | Conceptual foundation |
| Physics | Concepts of Physics Vol 1 and 2 | HC Verma | Conceptual clarity and problems |
| Physics | DC Pandey NEET Objective Physics | DC Pandey | MCQ and NVQ practice for NEET pattern |
Q1. Is the NEET UG 2027 syllabus different from 2026? No changes have been announced as of May 2026. The 2027 syllabus is expected to follow the NMC-revised 2024 syllabus that applies to NEET 2025 and 2026.
Q2. How many chapters are in the NEET UG 2027 syllabus? Approximately 79 chapters total: around 38 in Biology (Botany + Zoology), 21 in Chemistry (Physical + Organic + Inorganic), and 20 in Physics across Class 11 and Class 12.
Q3. Is NCERT enough to score 600+ in NEET? For Biology, NCERT is sufficient for approximately 80 to 90 percent of the questions. For Chemistry, NCERT covers Inorganic and basic Organic well; Physical Chemistry needs additional numerical practice. For Physics, NCERT is necessary but not sufficient; HC Verma and DC Pandey are needed for concept application.
Q4. Which subject is most important in NEET? Biology is the most important subject, carrying 360 marks out of 720 (50 percent). A candidate who scores 340 to 360 in Biology and 130 to 140 each in Chemistry and Physics can easily cross 600 marks. Neglecting Biology is the single biggest strategic mistake in NEET preparation.
Q5. Is Communication Systems removed from NEET 2027 Physics? Yes. Communication Systems was removed from the NEET syllabus as part of the NMC 2024 revision, aligning with the updated NCERT textbooks that removed this chapter. Do not invest time in it.
Q6. How should I balance Class 11 and Class 12 for NEET? Class 11 and Class 12 contribute roughly equally across all three subjects. In Biology, Class 12 chapters (Genetics, Evolution, Ecology, Biotechnology) have consistently higher weightage in recent years. In Physics and Chemistry, Class 12 carries slightly more weight (approximately 55 to 60 percent of questions). Never neglect Class 11 entirely.
