Hello Manthan, 

Congrats for your score but as you've not mentioned the examination in which you secured this rank, i will not be of much help but i guess it's either of Jee mains or Comedk. 

So if it is of Jee Mains then you are eligible for any branch in most of the colleges as your score is really fabulous and if you've secured this rank in comedk then also you have some chances that you can procure a seat in a college through comedk in civil engineering branch.
