How to Use This PYQ Data
- Biology first. Start solving Biology PYQs immediately — it has the highest repetition rate and is 50% of the paper.
- Solve chapter-wise, not paper-wise. Complete all 10 years of 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.
- 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.
Analysis based on NEET papers from 2015–2025. Pre-2019 papers (AIPMT era) are included as the core syllabus remains the same. Individual year distributions may vary ±15% from averages. Last updated: February 2026.

Do NEET questions repeat from previous years?
Exact questions do not repeat, but concepts repeat heavily. Based on 10-year analysis, 40–50% of NEET questions test concepts that appeared in previous papers. Biology has the highest repetition rate (50%+) because NCERT content is finite and testable facts are limited. Solving 10 years of PYQs gives you a significant advantage.
How many years of NEET PYQs should I solve?
Minimum 5 years (2021–2025) for familiarity with the current pattern. Ideally 10 years (2015–2025) for comprehensive coverage. Solve chapter-wise first to identify weak areas, then solve full papers under timed conditions. For Biology, solving PYQs is the single highest-ROI activity after reading NCERT.
Which Biology chapters have the most questions in NEET?
Top 5: (1) Human Physiology — 10–12 questions per paper, (2) Genetics & Evolution — 8–10 questions, (3) Ecology — 6–8 questions, (4) Plant Physiology — 5–6 questions, (5) Cell Biology — 4–5 questions. These 5 units cover 60% of Biology marks. Prioritise them heavily.
Is solving NEET PYQs enough to score 600+?
PYQs alone can help you score 500–550. For 600+, you also need: (1) NCERT read 5+ times for Biology, (2) Reference book practice for Physics and Chemistry numericals, (3) 20+ full-length mock tests. Use PYQs as 40% of your practice strategy, not 100%.
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. If you solve 10 years of Biology PYQs chapter-wise, you will recognise 40–50% of question patterns in the actual exam. Chemistry PYQs are second most useful (especially Inorganic). Physics PYQs are least predictable but still valuable for understanding question difficulty.
