The JEE Main 2027 Class 11 syllabus is the NTA-prescribed set of topics from NCERT Class 11 Physics, Chemistry, and Mathematics that form part of Paper 1 (B.E./B.Tech). Class 11 contributes about 45–50% of JEE Main questions, and Class 11 topics — particularly Mechanics, Algebra, and Physical Chemistry basics — form the conceptual foundation for Class 12 topics.
The JEE Main 2027 syllabus has been confirmed by NTA with no new changes compared to 2025. The revisions made in 2024, based on NCERT rationalisation, continue to apply. Students who are already following the current NTA-revised syllabus need not change anything.
The JEE Main 2027 Class 11 syllabus covers 11 units in Physics, 12–13 chapters in Chemistry, and 9–10 units in Mathematics from NCERT Class 11. NTA has confirmed no new changes for 2027. The deletions made in 2024 — s-Block Elements (partial), Polymers, Communication Devices, etc. — continue to apply. The official 2027 information brochure with PDF is expected around October 2026 on jeemain.nta.nic.in.

Physics in JEE Main is split into Class 11 (mechanics-heavy) and Class 12 (electrodynamics-heavy). Class 12 topics carry slightly higher overall weightage, but Class 11 mechanics forms the backbone of your entire Physics understanding.
For Physics prioritisation: Mechanics + Electrodynamics + Optics + Modern Physics account for approximately 75% of the Physics paper. Within Class 11, Mechanics alone contributes around 30% of the Physics section.

NTA has confirmed no new changes to the JEE Main 2027 syllabus compared to 2025. The revisions made in 2024, based on NCERT rationalisation, continue to apply for 2027.
| Subject | Chapter / Topic | Class | Status |
| Physics | Communication Systems / Communication Devices | 12 | Fully Deleted (2024) |
| Mathematics | Mathematical Reasoning | 11 | Fully Deleted (2024) |

| Chemistry | Polymers | 12 | Fully Deleted (2024) |
| Chemistry | s-Block Elements (certain sub-topics) | 11 | Reduced (2024) |
For Class 11 students specifically: Environmental Chemistry and Mathematical Reasoning are the two Class 11 deletions that directly affect your preparation. Do not invest any time in these chapters for JEE Main 2027.
A very common confusion among fresh Class 11 students is whether CBSE board preparation is enough for JEE Main. The chapters are the same, but the depth required is very different.

No. NTA has confirmed no new changes to the JEE Main 2027 syllabus compared to 2025. The 2024 rationalisation-based deletions continue to apply. Students following the current syllabus are fully aligned.
No new Class 11 chapter has been deleted for 2027. The only Class 11 deletions in effect remain from the 2024 revision: Environmental Chemistry (Chemistry) and Mathematical Reasoning / Mathematical Induction (Maths). All other Class 11 chapters remain in the syllabus.
There are 11 core chapters: Units & Measurement, Kinematics, Laws of Motion, Work-Energy-Power, Rotational Motion, Gravitation, Properties of Matter & Fluids, Thermodynamics, Kinetic Theory of Gases, Oscillations (SHM), and Waves. Communication Systems (Class 12) is deleted and does not affect Class 11 Physics at all.
Rotational Motion (Physics) is consistently the highest-weightage individual chapter from Class 11, contributing an estimated 6–8% of Physics section marks per paper. In Maths, Calculus (Limits & Derivatives) and Conic Sections are equally critical from Class 11.
Rotational Motion is a Class 11 chapter (NCERT Class 11, Chapter 7 — Systems of Particles and Rotational Motion). It is one of the most important chapters in the entire JEE Main syllabus.
Class 11 Maths for JEE Main 2027 covers 9–10 units: Sets Relations & Functions, Trigonometric Functions, Complex Numbers & Quadratics, Sequences & Series, Straight Lines, Conic Sections, Limits & Derivatives, Permutations & Combinations, Binomial Theorem, and Statistics. Mathematical Reasoning is deleted and Mathematical Induction is negligible.
Class 11 contributes about 45–50% of JEE Main questions. Class 11 topics form the conceptual foundation for Class 12 topics, making them equally if not more important in terms of overall preparation.
The chapter list is the same (both from NCERT Class 11), but the depth, question style, and difficulty are very different. JEE Main requires multi-step application problems well beyond board exam expectations. Some chapters present in CBSE (like Environmental Chemistry) are deleted from JEE Main, and vice versa.
Chemical Bonding & Molecular Structure is the most important Class 11 Chemistry chapter, with an estimated 6–8% weightage. Thermodynamics and Equilibrium are close seconds, each at 5–7%. These chapters build the base for Organic Chemistry, Electrochemistry, and all other advanced topics.
Yes. General Organic Chemistry — covering IUPAC nomenclature, electronic effects (inductive, resonance, hyperconjugation), carbocation/carbanion stability, and isomerism — is a Class 11 chapter and is the conceptual foundation for every Class 12 Organic Chemistry chapter in JEE Main.
Yes. Limits, Continuity, and Derivatives are part of the Class 11 JEE Main Mathematics syllabus. Calculus as a whole contributes approximately 35% of the Mathematics section — the single highest unit in JEE Main Maths. Mastering Limits & Derivatives in Class 11 is essential before Class 12 Integration and Differential Equations.
Month 1: Laws of Motion + Basic Chemistry Concepts + Trigonometry. Month 2: Rotational Motion + Chemical Bonding + Limits & Derivatives + Conic Sections. Month 3: Thermodynamics (Physics + Chemistry) + Equilibrium + Complex Numbers. Month 4: SHM, Waves, Gravitation + GOC + Hydrocarbons + Sequences & Series + P&C. Month 5: Remaining medium-priority chapters + chapter-wise PYQs. Month 6: Full Class 11 revision + mock tests.
Kinetic Theory of Gases is a Class 11 chapter (NCERT Class 11, Chapter 13). It carries medium weightage in JEE Main and is conceptually linked to Thermodynamics.
Physics: NCERT Class 11 (essential for theory and basic numericals), then DC Pandey or HC Verma for JEE-level practice. Chemistry: NCERT (primary, non-negotiable) then N. Avasthi for Physical Chemistry and MS Chauhan for Organic. Mathematics: NCERT first, then Cengage or Arihant for JEE-level problem sets. PYQs from any standard compilation are mandatory across all subjects.
From the very beginning of Class 11 — ideally April or May 2026 when the new academic session starts. Starting early gives you time to cover both Class 11 and Class 12 thoroughly before the January 2027 session. Students who start late in Class 11 face severe time pressure in Class 12 when new chapters must also be learned alongside full JEE revision.
No — JEE Main draws questions from both Class 11 and Class 12. However, strong Class 11 preparation, particularly in Rotational Motion, Chemical Bonding, Equilibrium, Calculus, and Conic Sections, is essential for reaching the 99 percentile. Toppers consistently demonstrate equal command over both years.
From jeemain.nta.nic.in. The official 2027 information brochure with the complete syllabus is expected in October 2026. Until then, students preparing for JEE Main 2027 should continue with the current reduced syllabus (2024 revision), available on jeemain.nta.nic.in, with a strong focus on high-weightage Class 11 and Class 12 chapters.
Yes. Environmental Chemistry was removed from the JEE Main Chemistry syllabus in the 2024 NTA revision and continues to be absent for 2027. Note that it may still appear in your CBSE board exam — prepare it for boards but do not allocate JEE Main preparation time to it.
