JEE Main Chapter Wise Weightage 2026: Subject-wise Weightage, Important Chapters, Previous Year Analysis
Content Curator | Updated On - Apr 4, 2026
What's New?
The National Testing Agency (NTA) does not officially publish any fixed chapter-wise or topic-wise weightage for JEE Main 2026 exam, but an approximate idea can be drawn from the past year’s question paper analysis. 1 to 5 questions are asked from each chapter and each Chapter of the JEE Main syllabus contributes around 3-10%. Chapters with high weightage carry 3-5 questions.
Understanding the Chapter-wise or Subject-wise weightage can help candidates to effectively manage their time and effort for this preparation. As per previous years’ trend, some of the Important high-weightage chapter for JEE Main 2026 are:
- Physics: Modern Physics has the highest weightage of approx 15.9%, followed by Optics, Heat and Thermodynamics, and Current Electricity, with a weightage of 9.9% .
- Chemistry: Highest weightage chapters of chemistry include Transition Elements and Coordination Compounds, Periodic Table and p-Block Elements at 9.9% weightage each chapter.
- Mathematics: The highest weightage of 16.6% goes to Coordinate Geometry, followed by Continuity and Differentiation and Integral Calculus (10% each).
