Hi Anubhav, normally getting into top MBA colleges is not possible without writing MBA entrance exams. Generally the top 100 colleges and IIMs expect entrance exams to be passed in order to provide admission. You can get MBA in some colleges where there is management quota or rather there are some colleges, which offer seats to fill up their quota. But the MBA degree provided would just be for name sake. Coming into the question, some of the colleges are, 

1) AMITY, Delhi 

2) Shiv Nadar University, Greater Noida 

3) BRIDGE school of management, Greater Noida

4) GD Goenka University, Greater Noida 

In my opinion, I would suggest you to take up atleast one entrance exam say MAT which is the easiest of all exams, and try to clear it with some amount of hard work, which confirms a seat in many good colleges, which not only provides a reputation but also some good Return of Investments as well. All the best
