What are the Deleted Topics for JEE Mains 2025?

As students prepare for the JEE Main 2025, one significant update to note is the revision of the syllabus. The National Testing Agency (NTA), which oversees the exam, frequently modifies the syllabus to ensure its alignment with modern academic standards.

This year, several topics across Physics, Chemistry, and Maths have been removed to help students focus on more relevant subjects. In this article, we'll not only outline the deleted topics but also provide an overview of the complete JEE Main 2025 syllabus, including subject-wise weightage.

JEE Mains 2025 Syllabus Overview 

The JEE Mains syllabus is designed to test a student’s proficiency in Physics, Chemistry, and Mathematics, primarily based on the 11th and 12th-grade CBSE syllabus. Understanding the weightage of each subject can help in prioritizing your study plan.

Subject Total Marks Key Topics
Physics 100 Mechanics, Electrodynamics, Thermodynamics, Optics, Modern Physics
Chemistry 100 Organic Chemistry, Physical Chemistry, Inorganic Chemistry
Mathematics 100 Algebra, Calculus, Coordinate Geometry, Vector Algebra

Each subject consists of two sections:

  1. Section A: 20 Multiple Choice Questions (MCQs)
  2. Section B: 10 Numerical Answer Type Questions (out of which 5 must be attempted)
