Joint Entrance Exam Main chapter-wise-weightage
The JEE Main chapter-wise weightage is not fixed by the NTA. As per the previous year's analysis, around 30-35% of questions in the JEE Main Exam appear from high-weightage chapters from physics, chemistry, and mathematics.
- In JEE Main Mathematics, 12-15 questions are from coordinate geometry, calculus, limits, Continuity and differentiability, making around 40-50 marks.
- In JEE Main Physics, topics like thermodynamics, Current Electricity and laws of motion together carry 15-20 marks, including numerical-based questions as well.
- In JEE Main Chemistry, chapters like Coordination Compounds, Hydrocarbons, and Periodic Table together contribute 35-40 marks.
As per the JEE Main paper analysis from previous years, each chapter of JEE Main 2026 carries 1-5 questions on average.
