I am sure that each school is different, but I will tell you how it works at PCOM to my knowledge. At PCOM you must first be accepted as a DO student. Then halfway through your first year you apply to the school you want to get your joint degree from, at pcom you must apply to the schools that they are partnerships with. If you want an MBA, you must go to St. Josephs, if you want an MS you must go to Temple, etc..... I know they take your MCAT and gpa into consideration, but there is also a minimum gpa and mcat that you must have for each school. I am sure if you contact your D.O. school of your choice they can tell you the minimum requirements for each joint degree program. Good Luck.
