NEET Chapter-Wise Weightage 2026: All 77 Chapters, Subject by Subject
NEET (UG) has 200 questions — 50 each in Physics, Chemistry, Botany and Zoology — drawn almost entirely from the NCERT Class 11 and 12 syllabus. But chapters are not weighted equally: a handful of chapters reliably contribute 3–5 questions every year while others give one at most. Revising in weightage order is the single highest-ROI scheduling decision you can make. The tables below show the chapter-wise distribution we use to assemble every centAIle mock, mirroring the official NEET blueprint.
How to use these tables
- Revise top-weight chapters first — a 5-question chapter at 80% accuracy is worth more marks than a 1-question chapter at 100%.
- Multiply weightage by your accuracy gap: a heavy chapter you're weak in is your highest-priority fix.
- Don't skip 1-question chapters entirely — together they still add up to 30+ questions across the paper.

Turn weightage into a revision plan
Weightage tells you where marks live; your own accuracy tells you where you're losing them. Cross the two and you get a priority list — exactly what centAIle's analysis does automatically after every mock: it finds your weakest high-weight chapters, estimates the recoverable marks in each, and converts them into a predicted rank improvement.
