JEE Main 2027 Syllabus: Complete Chapter List for Physics, Chemistry, Mathematics with Removed Topics

What Changed in the JEE Main Syllabus and Why It Matters

The NTA released a reduced JEE Main syllabus in November 2023 (effective from JEE Main 2024 onwards). This same reduced syllabus continues for JEE Main 2027 — the NTA has not announced further changes for the 2027 cycle.

What the reduction means in practice:

• Roughly 18-22% of the older JEE Main syllabus has been removed or reduced across the three subjects
• The total number of chapters tested is now smaller
• Students who use pre-2024 books or coaching material risk over-preparing on removed topics

This article gives you the complete current JEE Main 2027 syllabus with explicit notes on what was removed, so you can prioritise correctly.

3. Laws of Motion
4. Work, Energy and Power
5. Rotational Motion
6. Gravitation
7. Properties of Solids and Liquids
8. Thermodynamics
9. Kinetic Theory of Gases
10. Oscillations and Waves

Class 12 Topics

11. Electrostatics
12. Current Electricity
13. Magnetic Effects of Current and Magnetism
14. Electromagnetic Induction and Alternating Currents
15. Electromagnetic Waves
16. Optics (Ray + Wave)

Section B — Experimental Skills (20% Weight)

The experimental skills section tests practical-style questions on instruments, vernier calipers, screw gauge, ohmmeter, simple pendulum, etc. Five questions in this section, all integer-type.

Removed/Reduced Physics Topics (Compared to Pre-2024)

• Communication Systems — completely removed
• Semiconductor Electronics — reduced to "basic concepts of diodes" only; transistor characteristics out
• Laser, optical fibre, modulation — all removed

If your reference book covers these topics, skip them entirely.

10. p-Block Elements (Groups 13-18)
11. d- and f- Block Elements
12. Coordination Compounds

Organic Chemistry

13. Purification and Characterisation of Organic Compounds
14. Some Basic Principles of Organic Chemistry
15. Hydrocarbons (Alkanes, Alkenes, Alkynes, Aromatic)
16. Organic Compounds Containing Halogens
17. Organic Compounds Containing Oxygen (Alcohols, Phenols, Ethers, Aldehydes, Ketones, Carboxylic Acids)
18. Organic Compounds Containing Nitrogen (Amines, Diazonium Salts)
19. Biomolecules
20. Principles Related to Practical Chemistry

Removed/Reduced Chemistry Topics (Compared to Pre-2024)

• States of Matter — entire chapter removed
• Surface Chemistry — entire chapter removed

• Environmental Chemistry — entire chapter removed
• Polymers — entire chapter removed
• Chemistry in Everyday Life — entire chapter removed

This Chemistry reduction is the single biggest change. Roughly 8 chapters from older syllabi are no longer tested. Students using pre-2023 modules from coaching institutes are over-preparing significantly.

Class 11 vs Class 12 Weightage Distribution

Based on JEE Main 2024-2026 paper analysis:

Subject	Class 11 Weightage	Class 12 Weightage
Physics	40-45%	55-60%
Chemistry	40%	60%
Mathematics	35-40%	60-65%

This means students who postpone Class 11 revision until February-March will lose 14-15 questions worth of preparation. Class 11 chapters are not optional.

---

Marking Scheme (Unchanged for JEE Main 2027)

Each subject in JEE Main has 30 questions:

• 20 MCQs — +4 for correct, -1 for incorrect, 0 for unattempted
• 10 Numerical/Integer questions — +4 for correct, -1 for incorrect (changed from 0 in 2023; check NTA bulletin for 2027 final rules)

Total: 90 questions, 300 marks, 3 hours.

A common mistake is treating integer questions as "free attempts". With negative marking introduced, attempt only those integer questions where you are 75%+ confident in the answer.

How to Use This Syllabus for Preparation

Step 1 — Print this syllabus and tick off chapters as you finish them

A simple checklist gives you a visual progress bar that motivates daily completion better than any productivity app.

Step 2 — Cross-check coaching material against the removed list

If your coaching module covers removed topics (Surface Chemistry, States of Matter, Communication Systems, Mathematical Reasoning), skip those chapters entirely. Use the time saved on Mechanics, Coordinate Geometry, or Organic Chemistry.

Step 3 — Spend study time proportional to weightage, not chapter count

Mechanics has 5 chapters but 25-30% of Physics weightage. Modern Physics has 3 chapters but only 10-12% weightage. Allocate accordingly.

Summary Table — JEE Main 2027 Syllabus Quick Reference

Subject	Total Chapters	Removed Chapters (Pre-2024)	Class 11 Share	Class 12 Share
Physics	19 + Experimental	3-4 (Communication, parts of Semiconductors)	40-45%	55-60%
Chemistry	20	8 (entire chapters removed)	40%	60%
Mathematics	14	2 (Math Induction, Math Reasoning)	35-40%	60-65%
Total Tested Chapters	53	13-14	—	—

The candidates who score 99+ percentile in JEE Main 2027 will not be the ones with the largest syllabus coverage. They will be the ones with the smallest, sharpest coverage of exactly what is in this current syllabus — and zero time spent on removed topics.

Print the chapter list. Cross off chapters as you finish them. Verify your books and modules align with the post-2024 reduction. Everything else is execution.
