Hello Kota karthik

I hope you are doing good and fine

With reference to your query, I would like to inform you thatat 75.7 percentile your estimated rank would be around 248589 - 279450 . At this rank their are chances that you will get a seat in NITS like mizoram,meghalaya,nagaland but their are quite low chances of getting cse seat . I would advise you to start loooking for top universities like AMITY ,VIT ,SRM ,UPES where they can you admission and trust me their are much better than these low nits

Hope you found this answer helpful. Good luck for your future
