I agree with niceguy. My incoming class had a GPA of 3.3-3.4 with an avg MCAT of 18!!. This was right out of the dean of admissions mouth. When you have an open door policy it makes quite hard to keep respectable numbers. I am sure pod schools vary but by how much? They have no applicants. 24 on the MCATs!! No way, there are bright students in these classes with good stats for sure but they are not the majority in these schools. Unless schools were willing to pick up their standards and take in 50% less students. Of course they can not afford to do that so there you go. I believe some schools do no require an MCAT at all. That should tell you something.
I know application pools vary and they are cyclical blah, blah, but MD,DO,DDS schools etc will never have to compromise admission standards to a point where accepted applicant stats will drop to below national averages because their applicant pools will always remain large enough and talented enough to fill their classrooms with talented students. Plus they are a more promising career choice so naturally they will attract better students also.
