Hello Prashant,

You have a pretty good percentile so you do have a strong chance in getting into one of the NITs but nothing can be told with a 100% guarantee before the months of April.

I suggest you calculate your possible rank from the following formula or use the given link to find out the probable rank. Take help of the given formula to calculate the rank or visit the link -

JEE Main 2019 rank (probable) = (100- NTA percentile score ) X 874469 /100

Practice some more and sit for the JEE Mains that is to be conducted in April, if you are not satisfied with your probable ranking.

Good luck!
