Hello Degapudi. Welcome to Careers360. Congratulations for such a good percentile. I would like to tell you that the exact rank is not announced yet. The second exam will take place in the month of April. After that, ranks and cutoffs of various colleges will be released. For your reference, I am sharing the link of previous years cutoffs of NITs. You can refer to that and get an idea.
