NEET Concept Wise Weightage: Most Asked Topics by Subject

The most-asked NEET concepts in every subject, ranked by previous year questions from 2017 to 2026. Based on 2,376 dated NEET previous year questions from 2017 to 2026. Topics are grouped into Tier 1, Tier 2 and Tier 3. This is our own analysis, not an official weightage.

Tier 1 topics together hold the first 70% of a subject's questions, Tier 2 the next 22% and Tier 3 the last 8%. Topics marked "low evidence" have very few questions. Out-of-syllabus topics are left out. Concept counts include only questions that two of three reviewers placed in the same topic, so they are slightly lower than chapter totals. For the chapter view see NEET chapter wise weightage.

How to use this

Master Tier 1 concepts first, then move to Tier 2 and Tier 3. Each chapter link opens previous year questions with step-by-step solutions for that chapter, and the Concept Priority Question Bank inside the app orders practice the same way.

What is concept-wise weightage?
It ranks the individual topics inside each chapter by how many NEET questions they have had, so you can see which concepts to master first.
Is this the official weightage?
No. It is our analysis of dated previous year questions from 2017 to 2026. Out-of-syllabus topics are excluded. Topics with very few questions are marked as low evidence.
