Hi

To get admission in NIT, you need to give JEE Mains. You are eligible for JEE Mains 2019.

But at the time of admissions to NITs/IIITs/GFTIs-

You need to have secured minimum 75% marks in class XII or equivalent exam or be in the top 20 percentile in their class XII exam conducted by the respective board.

For SC/ ST candidates, the eligibility criteria is to secure 65% marks in class XII or equivalent exam.

All the best.
