Hey Shreethic,

Congratulations on qualifying Mains. As per your given percentile you can try for IIIT, cuz Seats In NITs are limited but you can try taking any side branch if you are okay with it. And Most You have to wait Till spot round to get into a good IIIT Or NIT but It's Risky though. 

Best of Luck, Be Positive

Hey there

Your JEE main percentile is too low so unfortunately you won't be able to get any of the nits or good branch in them so you should try private colleges like kiit, and other colleges in Bhubaneshwar also there are good colleges under webjee so you have good options. 

Good luck
