The JEE syllabus, weighted by the exam itself

Every chapter below carries its measured share of real JEE Main papers — the same weights your readiness /300 is built from. No editor's guesses.

How the numbers work

Chapter weight = its share of tagged previous-year questions. Mastery = guessing-corrected IRT, minimum 3 answers, test-capped ladder. Readiness = 300 × Σ weight × mastery over measured chapters. A chapter with fewer than 3 answered questions reads "—" rather than a number.

The chapters that carry the most marks

Measured share of its own subject's 100 marks, highest first. This is the order worth revising in when time is short — and each one links to what that chapter actually holds.
