JEE Main 2026 · measured from past papers

JEE Main Chapter-wise Weightage

JEE Main chapter-wise weightage lists what each of the 54 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 75-question JEE Main 2026 blueprint.

chapters: 54
on the paper: 75
total marks: 300

Weightage for every JEE Main 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.

JEE Main 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 JEE Main syllabus page lists the same chapters with their topics.
