Hello Nupur,

Incase have scored 73% in 12th and you belong to General or OBC category you are not eligible for NIT. The basic eligibility criteria of the NIT say that you need to have scored at least 75% in boards aur be in top 20 percentile of the board exams. There is however a relaxation of 10% for SC ST candidate so they need only 65% in boards. If you are SC ST candidate then you are eligible for NIT and you might even get NIT Surat with 96 percentile in JEE Mains.

I hope this helps. All the best.
