You have good score in MAT, but prior applying in any good colleges you should do some research to find out which are the colleges that provide proper educational facilties, faculties as well as placements. Apart from these you should also take into consideration the location as well as accreditatio

You should re appear for cat and get good percentile .Otherwise u will get average collage.
