Physics (JEE Main)

This is a complete, free study companion for Physics (JEE Main) — built around what the exam actually asks. The topics examiners repeat most are Moment of inertia and axis theorems, Connected bodies, pulley systems and Newton's laws, and Kirchhoff laws, resistor networks and Wheatstone bridge. The syllabus runs to 24 chapters. Below you'll find the full topic-frequency ranking, the exam paper pattern, every chapter, a step-by-step study plan, and the official downloads — everything in one place.

Everything here is free. We're an independent student resource, not the official JEE body, so always confirm the current syllabus and exam dates on the official JEE website before you rely on them.

How to study Physics (JEE Main) and score well

Start with the highest-frequency topics — In Physics (JEE Main), Moment of inertia and axis theorems, Connected bodies, pulley systems and Newton's laws, Kirchhoff laws, resistor networks and Wheatstone bridge, and Dimensional analysis and dimensional formulae appear again and again in past papers. Master these first — they return the most marks for the time you put in.
Practise with previous-year papers — Solve the last 5–10 years of JEE Physics (JEE Main) papers under timed, exam-like conditions. Past papers show exactly which topics repeat and how questions are worded.
Revise actively, not passively — Write a one-page summary for each of the 24 chapters — key definitions, formulas and the points examiners reward — then re-test yourself instead of re-reading.
Mark your answers with the official scheme — After each practice paper, score yourself against the official marking scheme. It shows how marks are awarded step-by-step, so you learn to present answers the way examiners expect.

Exam tips: how to score higher in Physics (JEE Main)

Where students lose marks: rushing the high-weightage questions, skipping the steps the marking scheme rewards, and saving easy sections for last. Read the whole paper first, attempt your strongest section early to bank marks, and always show your working.

Manage your time: split your time in proportion to the marks each section carries, and keep a few minutes at the end to check. This paper carries negative marking, so attempt a question only when you can rule out at least one or two options — a blind guess costs you marks. Confirm the exact marking scheme for your session on the official portal.
