Your Exact rank cannot be precisely predicted. As your Jee mains 2021 score is 90 percentile ,  so your expected rank will be in range of 115000-140000 . Although it is expected rank, actual rank may differ from it.  With this rank your chances of getting seat in nits is very low, but yes you can get seat in other good colleges.
