If you are targeting MAT then if you get 95-100 percentile then only you can get a decent college like XIME or others that offers 60-80% placements. There are not many good colleges that accept MAT scores so you'll have to score really high to get a good college. Or else if you have not appeared for MAT yet then you can check out other management entrance exams like CAT that can guarantee you a good college even with a 70 percentile.

Good luck
