JEE Main · syllabus
The JEE Main 2027 syllabus for Paper 1 is expected to keep the 2026 structure: 20 units in Physics, 20 in Chemistry and 14 in Mathematics, all from Class 11 and 12. Below is the full unit list, what each unit contains, and where past papers put the most questions.
Quick answer
Paper 1 (B.E./B.Tech) tests Physics, Chemistry and Mathematics. Every question comes from the units below — nothing outside them is examinable.
Unit names follow the 2026 editions of the official syllabi. The 2027 syllabus had not been notified as of September 2026 — confirm against the official document when it is released.

BrainStride analysis of past papers · questions per paper, ranges vary by shift · NTA publishes no chapter weightage
BrainStride is an AI tutor for JEE, NEET and Olympiad preparation that runs a 20-minute diagnostic, maps your weak chapters and writes a daily plan, with every solution checked by teachers. We keep this syllabus page in step with the official NTA documents.
Not as of September 2026, because the 2027 syllabus has not been published. NTA releases it with the information bulletin, expected when registration opens around late October–November 2026. Until then, the 2026 unit list above is the one to study from. If NTA changes anything, we will update this page and the tracker.
The large cut came for JEE Main 2024, when NTA aligned the syllabus with the rationalised NCERT textbooks. In Chemistry, units such as States of Matter, Hydrogen and s-Block Elements no longer appear in the unit list. Topics were also trimmed inside units that stayed. Rather than rely on a list of deletions, compare your coaching material with the unit table above: if a topic isn't covered by a unit here, it isn't in the syllabus.
No. The 2025 change was to the paper, not the syllabus: all 75 questions became compulsory, 25 per subject, and numerical questions now carry −1 for a wrong answer. The units stayed the same. See the JEE Main exam pattern for the marking scheme.
The official syllabus is part of the information bulletin on jeemain.nta.nic.in — that is the only authoritative PDF. For a working copy you can tick off, open the syllabus tracker and use its Print button to save your list as a PDF.
The free 20-minute diagnostic maps your weak chapters against this syllabus, so you revise the units that leak marks first.
Neither can be skipped. By unit count the split is 24 Class 11 units, 21 Class 12 units and 9 that run across both years. Class 11 carries most of mechanics, physical chemistry basics and coordinate geometry, which later units assume you already know. Class 12 students who left Class 11 weak usually lose marks in Rotational Motion, Equilibrium and General Organic Chemistry.
No. Syllabus order is a filing system, not a study plan. Start with the units that feed others — Kinematics and Laws of Motion before Rotational Motion, Some Basic Principles of Organic Chemistry before any named reactions, Limits before Integral Calculus. Then weight your time by the ranges in the table above and by your own error rate.
Finishing the NCERT chapter and the coaching module is not the same as being done. A unit is done when you can solve its previous-year questions under time without looking anything up. Use previous-year questions chapter by chapter — the chapter-wise test generator plans the test — and mark a unit "done" in the tracker only after that.
The syllabus tells you what can be asked; four other pages tell you what to do about it. JEE Main eligibility covers the age rule, the attempt limit and the 75% board-marks condition for NIT and IIIT admission that catches students every year. The important dates page tracks the two 2027 sessions, and the answer key page explains how to score your response sheet when the provisional key comes out. The cutoff page shows the percentile that qualified for JEE Advanced each year, and the chapter-wise weightage analysis weights these 54 units by how often they are actually examined. If you are starting in Class 11, the Class 11 plan sets out the order; if JEE Advanced is the target, its syllabus still includes several chapters JEE Main dropped. The JEE Main hub links all of these.
Not as of September 2026. NTA publishes the JEE Main syllabus with the information bulletin, which is expected when registration opens around late October–November 2026. Until then, the 2026 syllabus — 20 Physics units, 20 Chemistry units and 14 Mathematics units — is the one to follow, since the unit list did not change between the 2025 and 2026 papers.
The JEE Main Paper 1 syllabus has 54 units: 20 in Physics, 20 in Chemistry and 14 in Mathematics. Many units cover more than one NCERT chapter — Optics, for example, spans Ray Optics and Wave Optics — so the count of textbook chapters you study is higher than the unit count.
Mostly, but not exactly. The JEE Main syllabus follows the Class 11 and 12 NCERT books closely, and was trimmed for 2024 to match the rationalised editions. The main exception is p-Block Elements, which JEE Main still lists even though the current NCERT Chemistry books dropped those chapters, so students study them from older NCERT editions.
NTA publishes no official chapter weightage for JEE Main. In BrainStride’s analysis of past papers, organic chemistry taken together brings about 7–9 questions per paper, calculus about 5–7, algebra about 4–6 and coordinate geometry about 3–5. In Physics, Modern Physics and Electrostatics repay effort fastest. These ranges vary between shifts.
The official JEE Main syllabus PDF is published by NTA on jeemain.nta.nic.in as part of the information bulletin. Other sites often repost older versions, so check the year on the document. For a tick-off copy, the free BrainStride syllabus tracker lists every unit and can be printed or saved as a PDF from your browser.
No. The JEE Main 2025 change affected the question paper, not the syllabus. The optional numerical section 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 the same as in the 2024 syllabus.
BrainStride is not affiliated with NTA. Always confirm the syllabus against the current official bulletin.
