JEE Main 2027 Syllabus — Complete Subject-Wise Topics List
JEE Main 2027 syllabus — the official NTA unit list for Physics, Chemistry and Maths, topics removed, approximate chapter weightage and study priorities.
The JEE Main 2027 syllabus is expected to be identical to JEE Main 2026. NTA hasn't published a 2027 syllabus yet, and the official 2026 syllabus is the same as 2025's. This guide gives you the complete topic list for Physics, Chemistry, and Mathematics as per NTA's 2026 syllabus, along with approximate weightage estimates from recent papers so you know where to focus your time. NTA itself publishes no chapter weightage.

About the weightage columns: the percentages below are approximate estimates from recent JEE Main papers, not official figures — NTA publishes no chapter weightage and the mix changes from shift to shift. Use them to set priorities, not to skip chapters.
Physics Syllabus — JEE Main 2027
Class 11 Topics

Class 11 Topics
| Unit | Chapters | Weightage (approx.) | Priority |
|---|---|---|---|
| Algebra | Complex Numbers, Quadratic Equations, Sequences & Series, Binomial Theorem, Permutations & Combinations | ~20% | High |
| Coordinate Geometry | Straight Lines, Conic Sections (Circle, Parabola, Ellipse, Hyperbola) | ~15% | High |

Class 12 Topics
| Unit | Chapters | Weightage (approx.) | Priority |
|---|---|---|---|
| Calculus | Limits, Continuity, Differentiability, Application of Derivatives, Integrals, Application of Integrals, Differential Equations | ~35% | High |
| Vectors & 3D | Vector Algebra, 3D Geometry (lines in space; planes are not in NTA's list) | ~10% | High |
| Matrices & Determinants | Matrices, Determinants | ~7% | High |
Mathematics prioritisation: Calculus + Algebra + Coordinate Geometry make up roughly 70% of Maths questions (estimate). These three areas should be your first priority. Within Calculus, focus on Integrals and Application of Derivatives, which usually account for several questions between them.
High-Priority Chapters — The 21 That Matter Most
If you are short on time, start with these 21 chapters. Based on recent papers they are among the most frequently tested (an estimate, not an official list):
| Physics | Chemistry | Mathematics |
|---|---|---|
| Kinematics | Mole Concept | Integrals (Definite + Indefinite) |
| Laws of Motion | Chemical Bonding | Application of Derivatives |
| Work, Energy, Power | Thermodynamics | Complex Numbers |
| Rotational Motion | Equilibrium | Sequences & Series |
| Electrostatics | Electrochemistry | Conic Sections |
| Current Electricity | Coordination Compounds | Matrices & Determinants |
| Optics (Ray + Wave) | p-Block Elements | Probability |
Syllabus Comparison: 2027 vs Previous Years
The JEE Main syllabus was significantly reduced for JEE Main 2024 (announced in November 2023), when NTA aligned it with the rationalised NCERT books. The 2025 and 2026 syllabi kept the same reduced format, and 2027 is expected to follow it. Key points:
- Communication Systems — removed from Physics.
- Mathematical Induction and Mathematical Reasoning — removed from Mathematics.
- 3D Geometry — now covers lines in space only (direction cosines, skew lines, shortest distance); planes are not listed.
- Electronic Devices — semiconductor diodes and logic gates; transistors are not listed.
- Chemistry — States of Matter, Surface Chemistry, s-Block Elements, Hydrogen, Isolation of Metals, Environmental Chemistry, Polymers and Chemistry in Everyday Life removed; p-Block is limited to general trends across Groups 13–18.
Do not waste time studying removed topics. Use the official NTA syllabus document on jeemain.nta.nic.in as your checklist.
How to Use This Syllabus Guide
- Print or save the topic tables above. Use them as a checklist — tick off each topic as you complete it.
- Start with high-priority chapters. Completing all "High" priority topics thoroughly covers most of the paper, but no chapter is ever guaranteed to appear.
- Match each topic to your textbook chapter. NCERT chapter names align closely with the syllabus topics listed above.
- Track weightage. Spend more time on high-weightage units. Mechanics (30% of Physics) deserves more hours than EM Waves (2%).
- Check NTA's 2027 information bulletin when it is released (expected around late October–November 2026) for any syllabus change.
Syllabus is based on NTA's official JEE Main 2026 syllabus (identical to 2025) and the 2026 information bulletin; NTA has not yet published the 2027 versions. Weightage percentages are approximate estimates from recent JEE Main papers — NTA does not publish chapter weightage. For the preparation roadmap, see our JEE 2027 preparation guide.

Start freeFrequently Asked Questions
Has the JEE Main 2027 syllabus changed from 2026?
NTA has not published a 2027 syllabus or announced any change. The official 2026 syllabus is word for word the same as 2025's; the last big revision was for JEE Main 2024, when NTA cut several topics to match the rationalised NCERT books. Prepare from the 2026 syllabus on jeemain.nta.nic.in and check the 2027 information bulletin when it comes out (expected around late October–November 2026).
How many chapters are in the JEE Main syllabus?
NTA's official syllabus is organised into 54 units: Physics 20, Chemistry 20 and Mathematics 14. They map closely onto the NCERT Class 11 and 12 chapters. Not all units carry equal weight — a smaller set of heavily tested chapters tends to account for a large share of questions, but NTA publishes no weightage, so any split is an estimate from past papers.
Which chapters have the highest weightage in JEE Main?
NTA does not publish chapter weightage. Rough estimates from recent papers: Physics — Mechanics (~30%), Electrodynamics (~25%), Optics & Modern Physics (~20%). Chemistry — Physical, Organic and Inorganic roughly a third each. Mathematics — Calculus (~35%), Algebra (~25–30%), Coordinate Geometry (~20%). The mix varies from shift to shift, so don't skip any unit.
Is the JEE Main and JEE Advanced syllabus the same?
No. JEE Advanced has its own syllabus, published by the organising IIT on jeeadv.ac.in. The two overlap heavily, but they are not identical, and JEE Advanced questions are far deeper and more multi-concept. Preparing for Advanced covers most of Main, but check both official syllabi — a few topics appear in only one of them.
Which chapters were removed from JEE Main syllabus?
For JEE Main 2024, NTA removed: in Chemistry — States of Matter, Surface Chemistry, s-Block Elements, Hydrogen, General Principles and Processes of Isolation of Metals, Environmental Chemistry, Polymers and Chemistry in Everyday Life; in Physics — Communication Systems and some experiments; in Maths — Mathematical Induction, Mathematical Reasoning and part of 3D Geometry. They stayed out in 2025 and 2026. Follow the current NTA syllabus, not older textbook content.
Should I study deleted chapters for JEE Main 2027?
No. NTA strictly follows the published syllabus. Studying deleted chapters wastes time that should go to high-weightage topics. Check the official NTA syllabus document and match it with the topics listed in this guide.
How should I prioritise chapters in JEE Main?
Divide chapters into three tiers: Tier 1 (high weightage + easy to score — do these first), Tier 2 (moderate weightage — do these next), Tier 3 (low weightage or very difficult — do these last if time permits). The priority tables in this guide follow this approach.
Is the Class 11 or Class 12 syllabus more important for JEE Main?
Both matter. NTA doesn't publish a Class 11 vs Class 12 split, but past papers draw roughly evenly from both. Class 11 topics (Mechanics, Algebra, Physical Chemistry basics) are also the foundation for Class 12 topics, so weak Class 11 basics hurt twice.
