Pankaj, Firstly,to be honest, your score is quite average and your chances of getting the top B-Schools are extremely small in case of general and even for OBC category as the good B-schools usually demand a score of close to 650- 700 for selection. However, you may still get a call from these colleges and you may apply for them:

Vellore Institute of Technology(VIT), Vellore

Alliance University, Bangalore

Lovely Professional University, Phagwara

Jaipuria institute of management, Jaipur

IIHMR University, Jaipur

AIMS Institute, Bangalore

Also, you can apply for other management entrance exams too as a lot of colleges accept other scores than MAT too for admission.
