Hello Aspirant, 

As you have not mentioned in which exam you have secured this rank but by seeing your interest in engineering, I guess this could be Jee Mains rank or Comedk rank. 

If it is Jee mains rank then you have all the doors open for government colleges like NITs and you can use the college predictor tool to predict the best suited colleges for yourself by using below provided link

Or if you have secured this rank in comedk then you have lesser chances of getting admission into good ranked colleges but still there are chances that you can secure a seat. 

The college predictor tool's link is provided here.

I will be able to help you better if you tell me about the exam in which you've secured this rank.
