NEET-UG Chapter-wise Weightage

NEET-UG chapter-wise weightage lists what each of the 72 chapters is worth on the paper. Each share is that chapter's proportion of its own subject, measured across 13,351 past-paper questions, and is turned into questions and marks using the 180-question NEET-UG 2026 blueprint.

chapters: 72
on the paper: 180
total marks: 720

Weightage for every NEET-UG chapter

These shares are measured across many years of past papers, so they describe the long run rather than predicting any single paper. "In the bank" is how many questions StudyBuddy has published for the chapter, which is a fact about this product rather than about the exam.

NEET-UG chapter-wise weightage: share of subject, typical questions, typical marks, and published questions per chapter.

Chapter weights are each chapter’s share of its own subject, so they sum to 100% within a subject rather than across the paper. The NEET-UG syllabus page lists the same chapters with their topics.
