Post-Bacc GPA?

I was looking at the University of Miami med school web page, and they said that they don’t consider Post-Bacc or Graduate grades when determining GPA. Does anybody know if this is a common practice at other medical schools?

From what I understand, AMCAS lumps your post-bacc with undergraduate to give a total undergraduate GPA. Your grad GPA is listed separately. I don’t know how Miami could not look at your AMCAS application and see this.
