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.
