## JEE Main 2021 Syllabus

NTA has released the syllabus for JEE main which is divided into 3 sections i.e. Maths, Chemistry, Physics. JEE main syllabus is composed of the Class 11th and 12th syllabus. The JEE main syllabus remains the same this year also. Candidates are advised to study each and every topic given in the JEE main syllabus.
