I got 45% in b.com.can i get good colleges for mba through good mat,xat or cmat scores?
Exams like CMAT, MAT and XAT have not there basic percentage requirement mentioned officially therefore you can apply.
Now the good thing is that your past academic records are also considered at a high level in CMAT/XAT/MAT and so if you score a good percentile and clear the interview and other selection rounds nicely then you can get admission in decent bschools through these exams.
You can even check the list of top colleges through these exams:

Good Luck!!
