Syllabus · JEE Main
Yes, Solid State is out of JEE Main — it left with the 2024 revision, along with Surface Chemistry, Polymers and several other chapters. No, p-Block Elements is not removed. NTA had not released a 2027 syllabus as of October 2026, so the 2026 list, below, is the one to plan against.
Quick answer
These chapters left the JEE Main unit list in the 2024 revision and are still out for 2026. Nothing further has been removed for 2027 — the 2027 bulletin had not been published as of October 2026.
| Chapter | Subject | In JEE Main? |
|---|---|---|
| Solid State | Chemistry | Removed |
| Surface Chemistry | Chemistry | Removed |
| States of Matter (Gaseous and Liquid) | Chemistry | Removed |
| Hydrogen | Chemistry | Removed |
| s-Block Elements | Chemistry | Removed |
| General Principles and Processes of Isolation of Metals | Chemistry | Removed |
| Environmental Chemistry | Chemistry | Removed |
| Polymers | Chemistry | Removed |
| Chemistry in Everyday Life | Chemistry | Removed |
| Communication Systems | Physics | Removed |
| Mathematical Induction | Mathematics | Removed |
| Mathematical Reasoning | Mathematics | Removed |
| p-Block Elements | Chemistry | Still in — not removed |
Compared against the current NTA unit list on our [JEE Main syllabus page](/jee-main/syllabus). Several surviving units also lost individual topics in 2024; check the bulletin for those. Most of the removed Chemistry chapters, Solid State included, are still in the [JEE Advanced syllabus](/jee-advanced/syllabus).
The questions students actually type, answered one line each against the current unit list. "2027" here means the syllabus you should plan on until NTA publishes the 2027 bulletin; nothing on this list has been announced as changing.
No — Chemistry. Removed in the 2024 revision and not restored. Still in the JEE Advanced syllabus.
Yes — Chemistry. Still a JEE Main unit (Groups 13–18) although the rationalised NCERT books dropped those chapters — study it from an older edition or your module.
No — Chemistry. Removed in 2024 with the s-Block unit.
No — Chemistry. Removed in 2024. Periodicity and the other inorganic units remain.
No — Chemistry. Removed in 2024. Gas-law ideas you need for Thermodynamics and Equilibrium are still examinable inside those units.
No — Chemistry. Removed in 2024. Still in JEE Advanced.
No — Chemistry. Removed in 2024.
No — Chemistry. Removed in 2024.
No — Chemistry. Removed in 2024.
No — Chemistry. Removed in 2024.
Yes — Chemistry. In the syllabus. Transition elements and lanthanoids/actinoids remain examinable.
Yes — Chemistry. In the syllabus as an organic unit.
Yes — Physics and Chemistry. In both subjects. Physics has Thermodynamics and Kinetic Theory of Gases; Chemistry has Chemical Thermodynamics.
No — Physics. Removed in 2024.
Yes — Physics. In the syllabus, usually one or two questions a shift.
Yes — Physics. In the syllabus; a short unit worth one question most shifts.
Yes — Physics. In the syllabus — the practical-based unit that students most often forget to prepare.
No — Mathematics. Removed in 2024.
No — Mathematics. Removed in 2024.
Yes — Mathematics. In the syllabus, usually one or two questions a shift.
Yes — Mathematics. In the syllabus.
Yes — Mathematics. In the syllabus (trigonometric functions, identities and equations, inverse trigonometric functions).
The harder question is which of the units still on the list are costing you marks. The 20-minute diagnostic maps them for you, free.
Two different things get called "the syllabus change" in coaching WhatsApp groups. Only one of them was a syllabus change.
| Cycle | What changed | Was it the syllabus? |
|---|---|---|
| JEE Main 2024 | Unit list aligned with the rationalised NCERT books. Units such as States of Matter, Hydrogen and s-Block Elements left the list, and topics inside surviving units were trimmed. | Yes — the real one |
| JEE Main 2025 | The optional "attempt 5 of 10 numericals" section was removed. All 75 questions became compulsory and numericals started carrying −1. | No — paper pattern |
| JEE Main 2026 | Same syllabus and same pattern as 2025, across both sessions. | No change |
| JEE Main 2027 | Syllabus not notified as of October 2026; Session 1 is tentatively 22–30 January 2027 per NTA’s calendar. Expected in the bulletin with registration. | Unknown — plan on 2026 |
Confirm every row against the official bulletin for your year before acting on it.
No. As of October 2026, NTA had not published the JEE Main 2027 syllabus. It arrives inside the information bulletin, which in recent cycles has come out with registration — expected around late October to November 2026. NTA’s examination calendar of 16 September 2026 already lists Session 1 tentatively for 22–24 and 28–30 January 2027, but a calendar is not a syllabus. Until the bulletin exists, the 2026 syllabus is the only list worth building a plan on.
This matters because September to November is exactly when "syllabus reduced for 2027" posts circulate. They are almost always one of three things: a screenshot of the genuine 2024 revision presented as new, a coaching institute's own topic list, or somebody's guess about which rationalised NCERT chapters will go next. A syllabus change is announced by NTA in the bulletin, and nowhere else.
The safe way to handle the gap is to work on the 2026 unit list and treat any deletion you hear about as unconfirmed. Adding a topic later costs you a week. Dropping a topic that turns out to be examinable costs you the marks it carried, twice over — once in the paper, once in the panic before it.
For JEE Main 2024, NTA trimmed the syllabus to match the rationalised NCERT textbooks. In Chemistry, whole units left the list — States of Matter, Hydrogen and s-Block Elements among them — and several surviving units lost topics inside them. Physics and Mathematics saw smaller edits of the same kind.
The current list runs to 20 units in Physics, 20 in Chemistry and 14 in Mathematics. Our JEE Main syllabus page sets out every one of them, and the syllabus tracker lets you tick them off as you finish them.
One exception is worth knowing, because it catches students who study only from the current books. p-Block Elements is still in the JEE Main syllabus even though the rationalised NCERT Chemistry books dropped those chapters. If your textbook doesn't cover it, you need an older NCERT edition or your coaching module for that unit — the syllabus, not the textbook, decides what can be asked.
The practical rule after any revision: don't hunt for a list of deletions. Compare your own material against the unit list in the bulletin, chapter by chapter. A topic that no unit covers isn't examinable; a unit your material skips is a gap you just found.
No. The 2025 change was to the question paper. The optional numerical section used from 2021 to 2024, where you attempted 5 of 10 numericals, was removed. Since 2025 the paper has 75 compulsory questions — 20 MCQs and 5 numericals per subject — worth 300 marks in 3 hours, with +4 for a correct answer and −1 for a wrong one on both question types.
That last detail changes how you should practise, even though not one topic moved. Under the old pattern a numerical you were unsure about was nearly free: you could skip it and attempt a different one. Now a guessed numerical costs a mark like any other wrong answer, and there is no menu to choose from.
So the 2025 change is really a change to your attempt strategy. Numericals have to be practised to the point of accuracy rather than acquaintance, and the decision to attempt one has to be made on whether you can finish it, not on whether you recognise it. The full breakdown is on the JEE Main exam pattern page.
The 20-minute diagnostic tests you across the current unit list and names the chapters where your marks leak — before you decide what to skip.
Officially, nothing. Every unit on the list can be asked, and in a 25-question subject paper a single unit you ignored can be the difference between two percentile bands.
The honest version of the question is about sequence, not deletion. With four or five months left and three subjects to hold together, you decide what to do first, what to do later, and what to meet only through mixed practice. Weightage helps with that ordering, as long as you remember NTA publishes none and every range you read — ours included — is somebody's reading of past papers.
Three rules keep the ordering sane:
The JEE Main hub collects the pattern, the important dates for the two 2027 sessions and the eligibility rules. Three of the units this post marks as heavy have chapter guides with formulas, worked questions and a quiz: definite integrals, coordinate geometry and electrochemistry. If JEE Advanced is the target, its syllabus still examines several of the chapters JEE Main removed in 2024, so do not delete them from your plan. Students a year out should start from the Class 11 plan, which orders these units for the first year.
Do this once when the bulletin lands, and again in December. It is the cheapest hour in your preparation.
Open the syllabus trackerNo. As of October 2026, NTA had not released the JEE Main 2027 syllabus. It is published in the information bulletin, which in recent cycles has appeared with registration — expected around late October to November 2026. Until then, prepare from the JEE Main 2026 unit list, which has been stable since the 2024 revision.
Solid State is not in the JEE Main syllabus. It was removed for JEE Main 2024, when NTA aligned the syllabus with the rationalised NCERT books, and it was not part of the 2025 or 2026 syllabus either. The 2027 syllabus had not been released as of October 2026. Solid State is still in the JEE Advanced syllabus, so study it if you are writing Advanced.
Nothing has been announced that changes it. The 2027 syllabus is published in the information bulletin with registration; until then the 2026 unit list — 20 Physics, 20 Chemistry and 14 Mathematics units, unchanged since the 2024 revision — is the one to prepare from. If the bulletin changes anything, compare it unit by unit rather than relying on a summary.
No. Hydrogen left the JEE Main unit list in the 2024 revision along with s-Block Elements. Hydrogen bonding and the hydrogen atom are still examinable where they belong to surviving units — Chemical Bonding, Atomic Structure and Atoms and Nuclei — so do not skip those topics.
No. p-Block Elements (Groups 13 to 18) is still a JEE Main Chemistry unit, even though the rationalised NCERT Class 11 and 12 books dropped those chapters. Study it from an older NCERT edition or your coaching module. Nothing has been announced that removes it for 2027.
Removed in the 2024 revision and still out: in Chemistry, Solid State, Surface Chemistry, States of Matter, Hydrogen, s-Block Elements, Isolation of Metals, Environmental Chemistry, Polymers and Chemistry in Everyday Life; in Physics, Communication Systems; in Mathematics, Mathematical Induction and Mathematical Reasoning. Nothing further has been announced for 2027.
Nothing has been announced for 2027. The last substantial removal was for JEE Main 2024, when the syllabus was aligned with the rationalised NCERT books and units such as States of Matter, Hydrogen and s-Block Elements left the list. Treat any other deletion you hear about as unconfirmed until the 2027 bulletin is published.
Closely, but not exactly. The JEE Main syllabus follows the Class 11 and 12 NCERT books and was trimmed for 2024 to match the rationalised editions. The main exception is p-Block Elements, which JEE Main still lists although the current NCERT Chemistry books dropped those chapters, so students study that unit from older editions or coaching modules.
No. The 2025 change affected the paper, not the syllabus. The optional section where you attempted 5 of 10 numericals was removed, so all 75 questions are compulsory, and numerical questions now carry −1 for a wrong answer. The Physics, Chemistry and Mathematics units stayed as they were in 2024.
No. JEE Advanced has its own syllabus, published by the organising IIT, and it includes chapters JEE Main does not list — Solid State and Surface Chemistry among them. If you are preparing for both, work from the JEE Advanced syllabus page as well, because the extra chapters are where students are usually caught short.
Not for JEE Main. Modules are often reused across years and exams, so they carry topics that left the JEE Main list in 2024 or that belong to JEE Advanced. Compare the module against the official unit list, and spend the time you save on previous-year questions from units that are still examinable.
NTA had not released the JEE Main 2027 information bulletin as of October 2026. Anything marked expected here comes from the 2025 and 2026 cycles, not from an official notice.
