How to use this data
- Only 1 topic appeared in three or more papers (24% of the chapter's questions), so repetition alone is a weak guide here. Cover the whole NCERT chapter.
- 24% were hard. After the basics, practise multi-step and application questions from the hard-tagged topics.
- Re-solve the 5 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.
