How to use this list

  • Foundations first. Units & Measurements, Motion in a Straight Line, Motion in a Plane and Laws of Motion look small, but later chapters depend on them.
  • Then the very high chapters. They earn the most marks per hour. Revise them more than once.
  • Never drop a chapter just because its tier is lower. One question can be the difference in rank.
  • Track it. Mark each chapter as started, done or due for revision, so you always know what is left.

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

How many chapters are in JEE Main 2027 Physics?

JEE Main Physics has 28 chapters: 14 from Class 11 and 14 from Class 12. The full list is on this page.

Which JEE Main Physics chapters have the highest weightage?

The heaviest are System of Particles & Rotational Motion, Current Electricity, Ray Optics & Optical Instruments, Semiconductor Electronics and Gravitation. In all, 8 Physics chapters are in the very high tier for JEE Main. Give them the most time, but finish the foundation chapters first.

Which Physics chapters should I study first?

Start with the foundation chapters: Units & Measurements, Motion in a Straight Line, Motion in a Plane, Laws of Motion and Work, Energy & Power. Later chapters build on them, even when they carry fewer direct questions. Then spend most of your time on the very high and high weightage chapters.
