Low on paper, not optional
These chapters rarely get many questions of their own, but other chapters are built on them. Skip them and the high-weightage chapters get harder.

How we rank chapters
We compared published analyses of past JEE Main papers from 2020 to 2025. The sources agree on which chapters come up most, but not on exact percentages, so we show tiers instead of numbers that look more precise than they are.
Chapters marked estimate have thin data, so treat their tier as a rough guide. Chapters marked Foundation may carry fewer direct questions, but other chapters depend on them. Do not skip them.
The chapter list follows the current NTA syllabus. The official 2027 syllabus comes with the information bulletin on jeemain.nta.nic.in. We update this page when it changes.
Questions students ask
Which chapters have the highest weightage in JEE Main?
Physics: System of Particles & Rotational Motion, Current Electricity and Ray Optics & Optical Instruments. Chemistry: Aldehydes, Ketones & Carboxylic Acids, Coordination Compounds and d- & f-Block Elements. Maths: Conic Sections, Complex Numbers & Quadratic Equations and Three Dimensional Geometry.
Can I skip low-weightage chapters in JEE Main?
Be careful. Some lower-weightage chapters, like Motion in a Straight Line, Some Basic Concepts of Chemistry and Relations & Functions, are foundations that other chapters depend on. Study those even if they rarely get their own question.
Why don't you show exact percentages?
Published analyses agree on which chapters matter most, but they disagree on the exact share by several points. Tiers are honest about that. A precise-looking number would not be.
Can I compare weightage across Physics, Chemistry and Maths?
Not directly. Each subject is ranked against its own chapters. Every JEE Main subject carries the same marks, so a very high Physics chapter and a very high Maths chapter are each among the most important in their subject.
