In the source data the Chemistry counts for 2024 and 2025 look unevenly split between the two years, so read those two years together rather than as separate trends.
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.
