I got national obc-pwd 604 rank in india 2018 in jee mains can i got any iit or nit?

Hi, saif

To get into the IITS and NITS, the competition is very high as they're the most reputated colleges under this.

With your less than 1000 all India rank, you have very good chances to get into the colleges of both IIT and NIT.

it would have been helpful, if you have given us your all India rank rather than giving us your category rank,

For the further information about the cutoffs of the IITS and NITS,  please check the link below
