Hello Pratyush,

To get admission in NITS, IIITs or GFTIs you must clear JEE Mains will a good rank in any category.

The total number of seats for under graduation program are 21,133 in all 31 NITs put together and around 27% seats are reserve for OBC candidate. So 21,133*27%=5706 so it's clear your not in any NITs, but you might get any other good government institute.
