NEET Previous Year Questions Chapter Wise — Repeated Concepts & Approximate Distribution
Approximate chapter-wise spread of NEET previous year questions in Biology, Physics and Chemistry, the concepts that repeat, and how to practise PYQs.
A large share of every NEET paper tests concepts that have appeared before. By approximate estimates from recent papers, Human Physiology (around 10–12 questions), Genetics & Evolution (around 8–10) and Ecology (around 5–6) are the most frequently tested Biology units. The tables below show the approximate number of questions each chapter gets and the concepts that come up again and again. NTA publishes no official chapter-wise data, so treat the counts as a guide.
NEET now has 180 compulsory questions — 45 each in Physics, Chemistry, Botany and Zoology. Chapters that are no longer in the NEET syllabus (such as Transport in Plants, Mineral Nutrition, Digestion and Absorption, Solid State and Metallurgy) have been left out, even though they appear in older papers.

How to Use This PYQ Data
- Biology first. Start solving Biology PYQs immediately — it repeats the most and is 50% of the paper.
- Solve chapter-wise, not paper-wise. Complete all recent years' PYQs for one chapter before moving to the next. This builds deep understanding of question patterns.
- After solving, read the NCERT line where the answer comes from. This reinforces your NCERT reading and helps you spot testable lines.
- Skip questions on dropped topics. Older papers include chapters that are no longer in the syllabus — check each question against the current NEET syllabus.
- Track accuracy per chapter. Below 70% accuracy means you need to revise that chapter's NCERT before solving more PYQs.
- Focus on "Very High" repetition chapters during the last month. These give the highest return in limited time.
Question counts are approximate estimates from recent NEET papers; NTA publishes no official chapter-wise data, and each paper varies. Chapters and concepts not in the current NMC syllabus (NEET-UG 2026 bulletin) have been left out.

Start freeFrequently Asked Questions
Do NEET questions repeat from previous years?
Exact questions rarely repeat, but concepts repeat heavily — a large share of every NEET paper tests ideas that have appeared before. Biology repeats the most because the NCERT content it is based on is finite. That is why solving previous years' papers chapter-wise gives you a significant advantage.
How many years of NEET PYQs should I solve?
At least the last 5 years (2022–2026; for 2026 use the 21 June re-exam paper, since the 3 May paper was cancelled), and ideally more. Papers before 2025 had 200 questions with Section B choices, and some older questions cover chapters that are no longer in the syllabus — skip those. Solve chapter-wise first to find weak areas, then full papers under timed conditions.
Which Biology chapters have the most questions in NEET?
By approximate estimates from recent papers: (1) Human Physiology — around 10–12 questions per paper, (2) Genetics & Evolution — around 8–10, (3) Ecology — around 5–6, (4) Plant Physiology — around 5–6, (5) Cell Biology — around 4–5. Together these are roughly 35–45% of the 90 Biology questions. NTA publishes no official chapter-wise data.
Is solving NEET PYQs enough to score 600+?
Rarely on its own. For 600+ you also need: (1) NCERT Biology read many times over, (2) reference-book practice for Physics and Chemistry numericals, (3) plenty of full-length timed mock tests — on screen, since NEET-UG is moving to computer-based testing from 2027. Treat PYQs as one important part of your practice, not all of it.
Which subject's PYQs are most useful in NEET?
Biology PYQs are the most useful — NEET Biology is heavily NCERT-based, and the same facts get tested repeatedly. Solving Biology PYQs chapter-wise helps you recognise many question patterns in the actual exam. Chemistry PYQs are the next most useful (especially Inorganic). Physics PYQs are less predictable but still valuable for understanding question difficulty.
