Hii, mine FEB 2015 MAT score is 93.78%ile, Xth-80%,XIIth-73%, and graduation B.com-58%. whether i apply or not?

You can surely apply to try luck, but your graduation score is a bit low. there are no cutoffs for graduation percentage but this may decrease your profile value and in great lakes they give a lot of score to profile. but still you can apply, it's better to try and see for urself.
