There are no such good government colleges accepting MAT scores. Government colleges like IISc Bangalore or the like accept CAT scores only. So if you want admission on the basis of mat scores and are looking for a college that would give you decent placements then the only option is going for private colleges like

MS Ramaiah Institute of Management

ICFAI Bangalore

AIMS Institute

Manipal Academy for higher education

NITTE school of management

If you are looking for a degree in Finance then the best choice will be ICFAI Bangalore since the group is best for financial management course.
