Class 11 vs Class 12 — Question Distribution
| Subject | Class 11 Questions (%) | Class 12 Questions (%) |
|---|---|---|
| Biology | ~45% | ~55% |
| Physics | ~45% | ~55% |
| Chemistry | ~40% | ~60% |
| Overall | ~43% | ~57% |
Class 12 has a slight edge in question count, but Class 11 topics are foundational. You cannot understand Class 12 Genetics without Class 11 Cell Biology, or Class 12 Electrochemistry without Class 11 Thermodynamics. Both years are equally important for preparation.

Has the NEET 2027 syllabus changed from 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. This page will be updated immediately if NTA releases any official changes.
Is NEET syllabus based on NCERT?
Yes, NEET syllabus is directly based on NCERT Class 11 and Class 12 textbooks for Biology, Physics, and Chemistry. About 85-90% of NEET questions can be answered from NCERT content alone. The chapter names in the NEET syllabus correspond directly to NCERT chapter titles.
Which Biology chapters are most important for NEET?
The highest-weightage Biology chapters are: Genetics (Principles of Inheritance + Molecular Basis), Ecology (Organisms and Populations + Ecosystem), Human Physiology (all chapters), Plant Physiology (Photosynthesis, Respiration), and Cell Biology. Together these cover about 70% of Biology questions.
How many chapters are in the NEET syllabus?
NEET 2027 syllabus covers approximately 97 chapters: Biology has about 38 chapters (Class 11: 22, Class 12: 16), Physics has about 29 chapters, and Chemistry has about 30 chapters. Not all chapters carry equal weight — focus on high-weightage chapters first.
Is Class 11 syllabus important for NEET?
Very important. Class 11 contributes about 40-45% of NEET questions. Critical Class 11 topics include: Cell Biology, Plant & Animal Morphology, Plant Physiology, Human Physiology, Mechanics (Physics), and foundational Chemistry chapters. Ignoring Class 11 means losing nearly half the paper.
Which chapters were removed from NEET syllabus recently?
Chapters removed or reduced in the 2023 syllabus revision include: Units and Measurements (reduced), Motion in a Plane (reduced), some Organic Chemistry topics, Environmental Chemistry (reduced), and parts of Biotechnology. Always check the official NTA notification for the final list.
Should I study from NCERT or reference books for NEET?
Start with NCERT — always. For Biology, NCERT is 90% sufficient. For Physics and Chemistry, use NCERT for theory and add reference books (H.C. Verma for Physics, N. Avasthi for Physical Chemistry) for problem practice. Never start a reference book before completing the NCERT chapter.
Is the NEET and JEE syllabus the same for Physics and Chemistry?
There is significant overlap (about 70-80%), but they are not identical. JEE has more mathematical rigor in Physics and more advanced Organic Chemistry mechanisms. NEET Physics is more conceptual and application-based. If you are preparing for both, prepare at JEE level and NEET is automatically covered.
