Hello Aryan,

To secure a seat in any of the NITs/IIITs/GFTIs you need to have secured the minimum cutoff percentage in 12th. For general category it is set at 75% or top 20 percentile of 12th board exams. But for SC/ST it is fixed at 65%. So as your percentage indicate, you are not eligible to get a seat in NITs/IIITs/GFTIs.
