First of all, congrats to you for such a fine percentile. According to the percentile vs marks criteria which can be calculated as given on NTA website, your rank can range from 22000-26500. You will get decent NIT with good to medium branch in this rank. Don't worry, branches in engineering can be changed if one has done excellent in 1st year od graduation.
