Frequently asked questions
Which concepts are repeated most in JEE Main?
Across 2022–2026 the most repeated concept in the dataset is Linear Differential Equation (Mathematics), with 79 questions across all shifts.
Do JEE Main questions repeat from previous years?
Concepts repeat often, though questions rarely repeat word for word. Solving previous-year questions shows which ideas JEE Main keeps coming back to.
Why do some concepts show a dash for recent years?
A dash means no questions on that concept were counted that year. Some concepts belong to chapters that are no longer in the JEE Main syllabus.
Does a repeated concept guarantee a question next year?
No. Past frequency is a trend guide, not a promise. Use it to prioritise, but cover the full syllabus.
Solve JEE PYQs on the concepts that repeat.
Solve JEE previous-year questions with solutions on Edurack.

Counts are compiled from Edurack's JEE Main last five-year analysis (2022–2026) and count questions across all shifts and sessions of each year. Because the number of shifts changes every year, trends compare each chapter's share of the paper among chapters still in the syllabus, not raw counts. Past frequency is a trend guide, not a prediction. Chapters marked "not in syllabus" are absent from NTA's JEE Main 2026 syllabus; always check the latest NTA syllabus before skipping a chapter.
