# JEE Advanced 2023 Revised syllabus Recently a revised syllabus for JEE Advanced 2023 has been announced by its organizing committee IIT Guwahati, and can be accessed from JEE Advance official Website  The revised syllabus does not have any major changes. It’s been said bye the expert that the reason for the changes made in the syllabus had been done by keeping National Education Policy 2020 in mind in order to match the NCERT curriculum. The focus of the exam has been shifted from concepts and theories to practical Applications.
