Hello aspirant,

Eligibility is published by the National Testing Agency (NTA). It is the main exam conducting authority which organizers Joint Entrance Examination (JEE Main). It is a national level examination which is conducted to provide admissions in various undergraduate engineering courses in IITs, NITs and IIIT's. The examination is being conducted four time. i.e February, March, April & May 2021 via online (computer based mode) mode. Before filling the application form candidates have to satisfy themselves with the eligibility criteria that they are eligible for the paper which they are applying for.

For JEE Mains there is a relaxation that you needn't have a minimum of 75% aggregate marks in class 12th Board exams. But as far as JEE Advanced is concerned, in my opinion you still need a score of minimum 75% to be eligible.

Hope this is helpful for you.

Thank you.
