Hello,
It's impossible to get any NIT at 79 percentile. You have better chances of admission in private colleges/state Government College rather than NITs.
The minimum closing rank for SC Category is around 8,000 to 9,000 but with your percentile this rank would be around 540016 to 64,000 so it is impossible for you to get admission in any NIT but however u have officially qualified for SC Category.. wait for Official cut-off and prefer to apply at your state NIT.
You can predict your college by the below given link also-
