Hey Utsav

thankyou for contacting career 360

As per career 360 predictor your rank will lie between 82,000-83,000 .There are less chances to get NIT. But this is just a rough idea . I would suggest you to re-appear in JEE Mains to be held in the month of April . Your final rank is declared on the basis of best of the two . So it can be beneficial for you to re-appear.

Hii

As of now the cutoffs for NIT have not yet been released so it is difficult to say whether you get admission or not.
But 90 percentile is a decent score and as per the predictions made by careers360 after collecting information from various coaching institutes and previous year trends, 85 percentiles candidates would get admission in NITs but its just an assumption, there is no confirmation so you need to wait for the official result to be out.
