Hey Sharmila,

With this much score in jee mains from OBC category you cannot get a good government college. I will suggest you to go for gftis like Mizoram University or Assam University if you belong to the home state quota of these universities. You should look for private colleges like:

Upes Dehradun

SRM University

Amity University

Chandigarh University etc.

I hope you have got the point. 

Good luck !
