JEE Main 2020 Syllabus

For Paper I

National Testing Agency (NTA) will hold JEE Main twice a year from 2019 onwards. The national level examination will be conducted only in the online mode (computer-based). Aspirants can opt for one or both the papers of JEE Main. JEE Main syllabus comprises of a list of all the concepts taught in class 11 & 12 Physics, Mathematics and Chemistry

The syllabus for JEE Main & Advanced has been similar over the past years and is set separately for Paper 1 & Paper 2. However, the distribution is slightly different in the exam pattern. Aspirants must rigorously practice with the sample papers to get an idea of marking scheme and the pattern of JEE Main Papers.

Here we have compiled a list of all the chapters covered in the syllabus of JEE Main. The topic wise weightage of JEE is highly uncertain, therefore, the students are advised to prepare the entire syllabus without skipping.
