Hello Ramkrishna, 

You have some decent score but still it is not sufficient for you to procure a seat in an IIIT or GFTI. 

But still if you want to pursue a technical course of Engineering then you can opt for some good ranked private universities or state Technical Universities like RTU, GTU, UPTU etc. 

These state colleges have lesser fee compared to universities and education quality is also very good. 

I'll be able to help you in much better way if you are interested in knowing more about these or you tell me your domicile.
