Hello dear student,

• Candidate should have passed class 12 or qualifying the exam in 2018 or 2019.

• Candidate appearing in class 12 or equivalent qualifying exam in 2020 can also apply for JEE Main.

From the board from which you are qualifying your class 12th should be recognised and as you have completed a going to complete your class 12th from NIOS which is national Institute of open schooling. And it is obviously a national board which is run by government itself so it counts .

I hope this was helpful

Thank you
