The JEE Main reduced syllabus was introduced by the National Testing Agency (NTA) to align the exam with the revised NCERT curriculum. The syllabus revision was first implemented in JEE Main 2024 and continues to apply for JEE Main 2026, with no major additional changes announced so far.
The revised syllabus removed several chapters and topics from Physics, Chemistry, and Mathematics, reducing approximately 15% of the overall syllabus while retaining nearly 85% of the original content.
The reduction was implemented to streamline the preparation process and ensure that the exam focuses primarily on core concepts from Class 11 and Class 12 NCERT textbooks.
Candidates preparing for JEE Main 2026 should carefully review the reduced syllabus to avoid spending time on topics that are no longer included in the examination. Understanding the updated syllabus helps students create a more efficient study plan and focus on chapters that carry higher weightage in the exam.

Why Was the JEE Main Syllabus Reduced?
The decision to reduce the JEE Main syllabus was made after revisions to the NCERT and CBSE curriculum for Classes 9–12. Many chapters were removed or shortened in school textbooks, and the entrance exam syllabus was updated accordingly.
Major reasons for the syllabus reduction include:
- Alignment with the updated NCERT syllabus
- Removal of less relevant or outdated topics
- Reduction of academic load for students
- Focus on conceptual understanding and core engineering fundamentals
- Standardization of syllabus with school curriculum
Another objective was to ensure that students preparing through the NCERT curriculum are not at a disadvantage while appearing for the exam.
Despite the reduction, the difficulty level of JEE Main remains unchanged, as the removed topics were mostly theoretical or less frequently tested. The remaining syllabus still includes all the core concepts required for engineering entrance examinations.
Overview of JEE Main Reduced Syllabus
The JEE Main syllabus covers topics from Class 11 and Class 12 Physics, Chemistry, and Mathematics, which form the core foundation for undergraduate engineering studies. The syllabus is designed to evaluate a candidate’s conceptual understanding, analytical ability, and problem-solving skills.
With the introduction of the reduced syllabus, NTA removed several chapters and subtopics that were either less relevant to engineering entrance examinations or already removed from the revised NCERT textbooks. However, the exam still retains the majority of important concepts that are necessary for technical education.
The JEE Main exam tests students across three subjects:
- Physics, which focuses on fundamental laws of nature and their applications
- Chemistry, which includes physical, organic, and inorganic chemistry concepts
- Mathematics, which evaluates analytical and logical problem-solving abilities
Even after the syllabus reduction, students are expected to have a strong conceptual understanding of core chapters because the competition level remains high and questions are often application-based.
| Subject | Approx. Reduction | Key Changes |
|---|---|---|
| Physics | Minor reduction | Removal of communication systems and some experimental concepts |
| Chemistry | Moderate reduction | Several inorganic and organic chemistry chapters removed |
| Mathematics | Minor reduction | Mathematical reasoning and induction removed |
Even after the syllabus reduction, the exam continues to cover the most important concepts from Class 11 and Class 12 PCM subjects, which form the foundation for engineering studies.
JEE Main Reduced Syllabus for Physics
Several topics were removed from the Physics syllabus to simplify the content and focus on fundamental physics principles that are essential for engineering entrance examinations.
| Unit | Deleted Topics |
|---|---|
| Communication Systems | Entire unit removed |
| Experimental Skills | Certain experimental concepts removed |
| Kinematics | Zero vector concept removed |
| Gravitation | Geostationary satellites removed |
| Current Electricity | Color coding of resistors removed |
| Oscillations | Free, forced and damped oscillations removed |
| Thermodynamics | Newton’s law of cooling removed |
| Fluid Mechanics | Reynolds number removed |
| Heat Engines | Carnot engine and efficiency removed |
| Waves | Doppler effect in sound removed |
| Current Electricity | Potentiometer principle and applications removed |
| Measurement | Accuracy and precision of measuring instruments removed |
The removed physics topics mainly belonged to experimental concepts, theoretical discussions, and application-based sections that were less frequently tested in previous JEE Main examinations.
By removing these topics, the syllabus now emphasizes core mechanics, electricity, magnetism, and modern physics, which form the backbone of most engineering concepts.
Students should note that the remaining physics syllabus still requires a strong understanding of mathematical applications and numerical problem solving. Questions in JEE Main Physics often test the ability to apply formulas, analyze physical situations, and solve multi-step numerical problems.
In recent JEE Main papers, the majority of physics questions have been asked from the following chapters:
- Mechanics and Laws of Motion
- Work, Energy, and Power
- Electrostatics and Current Electricity
- Magnetic Effects of Current
- Modern Physics
These chapters are considered high-weightage areas and should be prioritized during preparation.
JEE Main Reduced Syllabus for Chemistry
Chemistry experienced the largest reduction in syllabus, particularly in inorganic chemistry and environmental chemistry.
| Section | Deleted Topics |
|---|---|
| Inorganic Chemistry | s-Block Elements |
| Inorganic Chemistry | Hydrogen |
| Physical Chemistry | States of Matter |

| Metallurgy | General Principles and Processes of Isolation of Metals |
| Environmental Chemistry | Entire chapter removed |
| Organic Chemistry | Polymers |
| Organic Chemistry | Chemistry in Everyday Life |
| Organic Chemistry | Some topics from Alcohols, Phenols and Ethers |
| Atomic Structure | Limitations of Thomson and Rutherford models removed |
| Measurement in Chemistry | Significant figures and precision concepts removed |
The reduction in Chemistry syllabus has simplified the preparation process for many students because several memorization-heavy chapters were removed.
Topics such as Environmental Chemistry, Polymers, and Chemistry in Everyday Life were largely theoretical and involved extensive factual learning. Their removal allows students to spend more time mastering conceptual and reaction-based chemistry topics.
However, Chemistry remains one of the most scoring sections in JEE Main because many questions are directly based on NCERT concepts and formulas.
Students preparing for JEE Main should focus particularly on:
- Reaction mechanisms in Organic Chemistry
- Numerical problems in Physical Chemistry
- Conceptual understanding of Chemical Bonding and Coordination Compounds
A strong focus on NCERT textbooks and reaction mechanisms is usually sufficient to perform well in this section.
JEE Main Reduced Syllabus for Mathematics
Compared to Physics and Chemistry, the Mathematics syllabus reduction was relatively small. Most major mathematical concepts remain part of the exam.
| Unit | Deleted Topics |
|---|---|
| Mathematical Induction | Entire unit removed |
| Mathematical Reasoning | Entire unit removed |
