The JEE Main 2027 Syllabus has been released by the NTA. Major changes have been observed in the syllabus. This article provides the details of the subject-wise and unit-wise changes in the JEE Main 2024-2025 syllabus in comparison to the JEE Main 2023 Syllabus. Between 2023 and 2027, Mathematics, Physics and Chemistry all lose content, and Chemistry loses the most. The 2027 syllabus is identical to the 2026 one, so everything below applies to 2026 as well.
The NTA (National Testing Agency) has recently released the JEE Main Syllabus for the 2025 examinations. Many changes have been observed in the recently released syllabus. While some units have been entirely deleted in the latest syllabus, there are various topics also which are deleted from different units in the syllabus. It is crucial for the students to check these changes in the syllabus to prepare well for the upcoming exams. Check the detailed schedule of the JEE Main 2026 exams here. This article provides a detailed analysis of the deleted topics from the JEE Main Syllabus and a list of new topics which have been added in the syllabus.
