How to use this data
- No single topic dominates here. The 15 topics are spread widely, with 11 asked only once, so cover the whole NCERT chapter rather than a short list.
- 32% 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.
