Hello Rimon. Welcome to Careers360. I would like to tell you that the second exam of JEE MAINS will take place in the month of April. So you have to wait till the results of second exam comes out. Considering your percentile, you might get admission in one of the NITs. But this is just the prediction. Actual results may vary. I am sharing the link in which you can check previous years NITs cutoffs
