Hi student,

It would be difficult to tell the minimum qualifying percentile required for NITs as JEE Mains exam is being conducted twice a year by NTA for this time.

However, according to previous year statistics, more than 85 percentile in the exam would be enough to qualify for the JEE Advanced exam. This is not the exact percentile and will vary after the jee mains April examination.

Hope it helps.

Good luck.
