JEE Main is one of the toughest exams in India that enables students to take admission to the most prestigious engineering colleges across the country. With a vast syllabus and an ocean of chapters, it becomes very difficult for aspirants to cover all the topics. However, some of the chapters in different sections hold more weight in the

exam that impact the overall performance of the students. Therefore, it is very important for the aspirants to understand the impact of a single chapter in the JEE Main papers for the current and previous years. This article analyses the impact of the single chapters on JEE Main papers from 2022 to 2026.

JEE Main Papers: Chapter-Wise Trends from 2022 to 2026
The JEE Main papers comprise questions from the sections Maths, Physics and Chemistry, and you can check the trends of the chapters from these sections below:
Mathematics: Coordinate Geometry, Integral Calculus, and Algebra (including Matrices, Complex Numbers, and Quadratic Equations) regularly contribute 8 to 12 per cent of the paper each year.
Physics: Modern Physics, Current Electricity, Electromagnetism, Heat & Thermodynamics, and Optics appear with a higher frequency, each accounting for 9 to 17 per cent of total marks.
Chemistry: Coordination Compounds, p-block and d/f-block Elements, Thermodynamics, and Chemical Kinetics, with "do or die" chapters marked because they yield up to 8 to 10 per cent per exam.

Impact of Single Chapters on JEE Main Papers
The chapters which carry more weightage can make a tremendous impact. Check the point below to understand the impact of single chapters on JEE Main papers:
Mastering 5 to 6 such high-weightage chapters across the three subjects can enable a student to answer up to 35 to 45 per cent of the total questions, a crucial advantage for competitive ranking.
For instance, Modern Physics alone has contributed nearly 16 per cent in some JEE Mains, while topics like Coordinate Geometry have given up to 10 per cent of Mathematics marks in one paper.
2025–26 shifts show Mathematics gaining slightly more overall weightage up to 35 per cent as per the latest exam formats, while Physics and Chemistry share the rest.

Chapter-Wise Weightage for Single Chapters in JEE Main
Check the chapter-wise weightage of the important chapters for JEE Main 2026 based on the analysis of the current and previous years' papers below:
Subject | Chapter | No. of Questions (Approx.) | Avg. Weightage |
|---|---|---|---|
Maths | Coordinate Geometry | 5 | 10 per cent |
Integral Calculus | 2 to 3 | 6 to 10 per cent | |
Matrices & Determinants | 1 to 2 | 4 to 10 per cent | |
Physics | Modern Physics | 4 to 5 | 15 to 17 per cent |
Current Electricity | 3 | 10 per cent | |
Heat & Thermodynamics | 3 | 10 per cent | |
Chemistry | Coordination Compounds | 2 to 3 | 7 per cent 9 |
p-block/d-block Elements | 2 to 3 | 8 to 10 per cent | |
Thermodynamics | 1 to 2 | 5 to 8 per cent |
The specific target of concentrating on a small set of single chapters with continuously greater representation in JEE Mains can be directly and quantitatively influenced in the maximisation of scores as well as efficiency of preparation. This creates strategic prioritisation of the chapter, an important part of an effective JEE Main preparation plan between 2022 and 2026.

FAQs
Prioritising high-weightage chapters allows for efficient scoring. Students should focus on mastering these chapters first, practice related numerical and theory questions, and regularly analyse previous papers for trend shifts.
The weightages remain fairly consistent, though some years show slight shifts based on paper design and question patterns. Core topics generally maintain their importance across years.
No, official chapter-wise weightage is not published by NTA; these trends are derived from analysis of previous year papers and expert reviews.
Yes, focusing on around 7 to 10 highest-weighted chapters across Physics, Chemistry, and Maths can help you answer 30 to 40 per cent of the paper, which is often enough for qualifying and securing a good rank.
A top-weighted chapter can contribute approximately 8 to 18 per cent of questions in a subject, with chapters like Coordinate Geometry, Modern Physics, or Coordination Compounds sometimes having 4 to 5 direct questions per exam.
