JEE Main Chapter-wise Weightage: As the JEE Main 2026 Session-2 exam is scheduled to be conducted from 1st to 10th April 2026, students are keen to understand the paper patterns and high-yield topics in advance. Knowing the JEE Main chapter-wise weightage 2026 is crucial for those appearing in this session to align their final revision with actual exam trends. This analysis is prepared from the last five years of question papers, including JEE Main 2025, providing a strategic roadmap across Physics, Chemistry, and Mathematics.
Analysing the JEE Main chapter-wise weightage helps candidates identify recurring chapters, optimise revision time, and prioritise preparation based on actual exam trends rather than assumptions. This approach is particularly useful for spotting high-weightage chapters in JEE Main 2026 Session-2 that have consistently contributed a significant number of questions over multiple sessions.
JEE Main Chapter-wise Weightage – Past 5 Years Analysis
The past five years’ chapter-wise weightage of JEE Main offers a clear picture of topic recurrence and subject dominance. By studying this data, students can identify chapters that consistently contribute questions and avoid over-focusing on low-frequency topics. This trend-based analysis forms the foundation for understanding the highest weightage chapters in JEE Mains across Physics, Chemistry, and Mathematics.

JEE Main Class-wise Distribution of Questions– Physics
Knowing how much of the question came from Class XI and Class XII will be able to aid you in your preparation strategy. In both years, Class XII questions slightly dominated the paper. But still, Class XI also carries a lot of weight, particularly in the year 2024. Thus, ensure that your preparation takes both classes in equal proportion.

JEE Main Chapter-wise Weightage for Chemistry
The JEE Mains chemistry chapter-wise weightage is distributed across three major branches:
-
Organic Chemistry: Regular contribution from GOC, Aldehydes–Ketones–Carboxylic Acids, Amines, and Biomolecules
-
Physical Chemistry: Strong presence of Thermodynamics, Electrochemistry, Chemical Kinetics, and Solutions
-
Inorganic Chemistry: Coordination Compounds, d- & f-Block, and P-Block remain recurring
A common concern among aspirants is the salt analysis weightage in JEE Mains. Although its individual weightage is lower, Salt Analysis continues to appear intermittently and should not be skipped entirely, especially for balanced scoring.
