  • 10-year average (fact)
  • Weighted estimate (model)

Typical range: questions per paper in the middle eight of the ten papers, leaving out the single highest and lowest year (about the 10th to 90th percentile), each paper scaled to 180 questions. The ten-year average and the range are historical fact. The weighted estimate is a model: each paper's share, with recent papers counting more (half-life three years), and dropped syllabus removed. It is a guide to effort, not a forecast.

Coverage

How much of the chapter NEET has used

We split the chapter into 79 ideas. In ten years NEET built a question around 19 of them. Most of the chapter has never been asked, which is why learning it whole beats memorising past questions.

Topics

What repeats, topic by topic

Questions per topic in each year's paper. Topics that come every year are worth learning first.

06+questions in that year’s paper

  • Biomolecule Structure

    Expect a one-line factual recall item about Biomolecule Structure; a match-the-columns item (two lists, pick the correct pairing code) is the next most likely shape. Past framings centre on: match list on biomolecules and functions; definition recall.
