Hello there...

As you've mentioned your rank is 89000 in OBC category so I would like to tell you that it seems very difficult for you to get a seat in any of the NIT/IIIT.

You can try next time if you are left with your attempts of JEE or you can attempt other engineering entrances also like BITSAT/VITEEE/WBJEE etc to get good colleges.

You can join private institutions also in various states.

Thanks..

I hope it'll be helpful..
