Key Updates on the Deleted Syllabus of JEE Mains 2025 You Need to Know

The Joint Entrance Examination (JEE) Mains is one of the most important competitive exams in India for students aspiring to pursue undergraduate courses in engineering. With every year, the syllabus for JEE Mains gets updated, and in 2025, several changes have been introduced, including a few deletions from the syllabus. In this article, we will take a deep dive into the deleted syllabus of JEE Mains 2025, breaking it down by sections and providing insights into the key concepts that students need to be aware of.

Introduction to the JEE Mains 2025 Syllabus

JEE Mains 2025 syllabus is structured to test students’ understanding of three core subjects: Physics, Chemistry, and Mathematics. These subjects are divided into several units or modules, each of which covers a wide range of topics. The exam is designed to evaluate a student's knowledge and problem-solving abilities in each of these areas.

For 2025, there are certain deletions in the syllabus. These deletions primarily focus on topics that may not be directly relevant or have been moved to higher levels of education or different subjects. It's important for students to know these changes, as it allows them to focus their studies on the topics that are still part of the syllabus.

Deleted Syllabus of JEE Mains 2025

Here’s a breakdown of the topics that have been deleted from the JEE Mains 2025 syllabus, subject by subject.

Physics

Unit: Mechanics

Deleted: Elasticity and its applications

Reason: This topic, which involves the study of how materials deform under stress, is considered to be more advanced and not directly relevant to the JEE Mains level.

Unit: Thermodynamics

Deleted: Maxwell’s Relations

Reason: Maxwell’s Relations, though important in thermodynamics, are generally more applicable to advanced studies and are no longer a part of the JEE Mains syllabus for 2025.

Unit: Electromagnetic Waves

Deleted: Properties and Applications of Electromagnetic Waves

Reason: Electromagnetic waves are still important, but their applications are now considered part of more specialized higher-level physics courses.

Chemistry

Unit: Organic Chemistry

Deleted: Electrophilic Substitution Reactions in Aromatic Compounds

Reason: This topic has been removed because it is often better understood with more advanced chemical knowledge, and it is not as essential for JEE Mains.

Unit: Physical Chemistry

Deleted: Bohr’s Model of the Atom

Reason: The Bohr Model has been replaced by more modern atomic theories, so it's no longer included in the syllabus.

Mathematics

Unit: Algebra

Deleted: Properties of Determinants

Reason: While determinants are a fundamental concept in higher mathematics, their properties are deemed less critical for the JEE Mains exam.

Unit: Coordinate Geometry

Deleted: Polar Coordinates

Reason: The topic of polar coordinates is removed, focusing more on practical and directly applicable concepts for the exam.

Detailed Breakdown of the 2025 Syllabus

Now that we know the deleted topics, let’s focus on what’s still a part of the JEE Mains 2025 syllabus.

Physics

Mechanics: This unit includes topics like Newton's Laws of Motion, Work, Energy, and Power, Motion in a Straight Line and Plane, and the Laws of Gravitation. You’ll learn to apply these concepts to solve various problems involving forces and motion.

Thermodynamics: Here, students will study concepts like laws of thermodynamics, heat engines, and enthalpy. The focus is on understanding energy transformations and their applications.

Electromagnetism: Key concepts like electrostatics, current electricity, magnetic effects of current, and electromagnetic induction are part of this unit. These topics test your understanding of how electricity and magnetism interact.

Chemistry

Physical Chemistry: Topics like Mole Concept, Chemical Kinetics, and Chemical Equilibrium are crucial. Students will learn about the nature of chemical reactions, reaction rates, and equilibrium constants.

Inorganic Chemistry: This includes periodic table trends, p-block elements, and d-block elements. You’ll understand the characteristics and behavior of elements based on their position in the periodic table.

Organic Chemistry: This section covers topics like Hydrocarbons, Alcohols, Ethers, and Carbonyl Compounds. You'll explore various organic reactions and their mechanisms.

Mathematics

Algebra: Includes topics like Complex Numbers, Matrices, and Determinants (excluding the properties of determinants). Students will learn to manipulate complex numbers and matrices to solve various types of problems.

Calculus: Topics like Limits, Differentiation, Integration, and Differential Equations will form the basis of this unit. You will develop skills to solve problems involving rates of change and areas under curves.

Coordinate Geometry: This unit deals with the Cartesian coordinate system, straight lines, circles, and conic sections (parabola, ellipse, hyperbola).

Exam Pattern and Weightage

The JEE Mains exam typically consists of multiple-choice questions (MCQs) and numerical answer type questions. Here’s an overview of the exam structure:

Number of Questions: 90 (30 each from Physics, Chemistry, and Mathematics)

Type of Questions: 75% of questions will be MCQs, while the remaining 25% will be numerical problems.

Marks Distribution: Each question carries 4 marks, with negative marking for incorrect answers (-1 mark).

In terms of weightage, the sections of the syllabus generally have the following distribution:

Physics: 33%

Chemistry: 33%

Mathematics: 34%

Recommended Study Materials

To prepare effectively for JEE Mains 2025, here are some of the top books and resources:

Physics: Concepts of Physics by H.C. Verma, Problems in General Physics by I.E. Irodov
