Average of all schools combined? I don't know. Stay in the 3's or you've got a battle ahead of you. There is a BCP GPA calculated with your application.
WOW! I just looked up more info - apparently my BCP is A LOT lower than my science. Unless I'm doing it wrong... I know premed forums have an AMCAS BCMP GPA calculator.. is there an excel file floating around here to calculate BCP?
