What is JEE Main 2026 Chapter-Wise Weightage?
JEE Main chapter-wise weightage refers to the percentage of questions asked from each chapter based on historical exam data. The weightage is calculated by analyzing question distribution across multiple exam sessions. Chapters with consistent high question frequency are termed high-weightage chapters. Students who focus on these chapters first typically score better in the exam.

Frequently Asked Questions
Calculus alone contributes around 30-35% of the Mathematics section based on past five years analysis. This includes Limits, Continuity, Differentiation, and Integration. Mastering Calculus can fetch 7-9 questions worth 28-36 marks. Reddit users suggest practicing at least 50 problems daily from Calculus chapters for consistent scoring.
Organic Chemistry contributes approximately 30-35% of the total Chemistry section. High-weightage chapters include General Organic Chemistry, Aldehydes and Ketones, and Amines. Quora discussions reveal that students who master reaction mechanisms score consistently in Organic Chemistry questions.
Priority chapters include Calculus, 3D Geometry, Current Electricity, Electrostatics, Coordination Compounds, and Organic Chemistry reactions. These chapters together contribute over 50% of the total paper. Focus on these first before moving to other topics.
NCERT is sufficient for Inorganic Chemistry where 80-90% questions come directly from NCERT. For Physical Chemistry and Organic Chemistry, supplement NCERT with reference books. Reddit users recommend reading NCERT thoroughly at least 3-5 times for Chemistry preparation.
Use weightage to prioritize topics, not to skip chapters. Secure all high-weightage chapters first with 80%+ accuracy. Then do quick NCERT-level revision of remaining chapters. Complete the entire syllabus as questions can appear from any topic.
Weightage shifts slightly each year but high-weight chapters remain consistent. Calculus, Mechanics, Electrostatics, and Organic Chemistry have maintained high weightage for the past 10 years. Minor variations occur based on paper setters but core patterns remain stable.
Class 12 has slightly higher weightage at approximately 51-55%. However, Class 11 contributes nearly 45-49% of questions. Both classes are equally important. Ignoring Class 11 topics is not advisable as they form the foundation for Class 12 concepts.
Each subject has 25 questions worth 100 marks. This includes 20 MCQs and 5 Numerical Value Questions per subject. Total paper consists of 75 questions worth 300 marks. All questions are compulsory with no optional questions available.
