How to use this data
- Only 1 topic appeared in three or more papers (10% of the chapter's questions), so repetition alone is a weak guide here. Cover the whole NCERT chapter.
- 45% of tagged questions were easy, so NCERT lines, definitions and standard examples are worth locking in first.
- Re-solve the 3 topics from NEET 2026 and Re-NEET 2026, since they show the current style of questions.
- Then attempt the chapter's past questions under a timer and note which topics cost you marks.
