Frequently asked questions
How many chapters cover most of JEE Main?
Physics: 14 of 20 chapters cover 80% of questions in 2024–2026; Chemistry: 14 of 20 chapters cover 80% of questions in 2024–2026; Mathematics: 10 of 14 chapters cover 80% of questions in 2024–2026.
Can I skip the low-weightage chapters?
They carry fewer questions, but they still appear. Treat the ranking as a study order, not a reason to leave chapters out.
How is the running total calculated?
Each chapter's share of 2024–2026 questions from chapters still in the syllabus is added to the ones above it.

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.
