# JEE Main 2024 Syllabus Reduced, Check Subject-wise Deleted Topics

National Testing Agency (NTA) released the revised JEE Main 2024 Syllabus. There has been a considerable reduction in the JEE Main Syllabus 2024 from all three sections-Physics, Chemistry, and Mathematics. The topics that are no longer included in Classes 11 and 12 syllabi have been removed from the JEE Main 2024 Syllabus.

A few topics have also been added to the Physics and Chemistry syllabus for JEE Main 2024. No new topic has been added to the JEE Main Maths Syllabus. Candidates can download the revised JEE Main Syllabus from* jeemain.nta.nic.in.*

Joint Entrance Examination (Main) or JEE Main is a national-level entrance exam for admission to various engineering courses in 31 NITs, 25 IIITs, 19 GFTIs, and other engineering colleges. For admission to IITs, candidates need to clear JEE Main and appear in the JEE Advanced exam. JEE Main exam is conducted by NTA, twice every year. JEE Main 2024 Session 1 will be conducted from January 24- February 1, 2024, and Session 2 will be conducted from April 1-15, 2024.
