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 the entrance exam 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  • To eliminate redundant and outdated content.

Q&A Icon
Commonly asked questions
Q:   Is JEE Main syllabus tough?
A: 

JEE Main syllabus is based on class 11 and 12 Physics, Chemistry and Maths topics. If you have focused while studying, then it will be easy to prepare for the exam otherwise, you may find it difficult. NCERT textbook is the best for Chemistry and Physics. You can also refer to other books for exam preparation. There are many preparation books suggested by the toppers of Joint Entrance Examination Main.   

Q:   In how much time can I complete the entire JEE Main syllabus?
A: 

Time required to cover JEE Main syllabus changes from one student to another student. In general, to complete the entire JEE Main syllabus, students would require around 1 year.

JEE Main paper 1 syllabus consists of Physics Chemistry and Mathematics. Paper 2A syllabus has Mathematics, General Aptitude and Drawing while Paper 2B syllabus has Mathematics, General Aptitude and Planning. Candidates must note that Mathematics syllabus is common/same in all three papers.
Q:   Can I complete JEE Main syllabus in 6 months?
A: 

JEE Mains syllabus can be completed in 6 months considering that almost every topic of JEE syllabus is similar to class 11 and 12 syllabus.
