I got 80.38 percentile in JEEMAINS . As I am from general category ,which college can I get?

This percentile isn't enough for a general category student to get admission into NITS or IIITS as for that you need to have a percentile more than 97%. Though you could get admission into some average a private colleges affiliated to jee mains. The official cutoffs for colleges and courses isn't released yet hence you need to wait for it to be more specific about the options you have.
Hope it helps.
Thank you.
