JEE Main 2027 Syllabus Deleted
The JEE Main 2027 syllabus will continue to align with the rationalised NCERT Class 11 and 12 textbooks, maintaining the major syllabus reductions implemented by the National Testing Agency (NTA). The following breakdown details the chapters and topics deleted across Physics, Chemistry, and Mathematics.
NTA reduced the JEE Mains syllabus due to the following reasons:
- To sync JEE Mains with the post-COVID rationalised school curriculum and to minimise student stress.
- The NTA committee consulted with over 40 education boards from various states and the central government in India. The aim was to create a fair starting point so that candidates from different regional boards would not be unfairly affected by topics missing from their local courses.
- To align the syllabus with the National Education Policy (NEP) 2020 guidelines.
- To eliminate redundant and outdated content.
