This is an interesting topic that has baffled me for years.
At my school (or possibly at any other prestigious "state" school that is known for their pharmacy program), I've seen A LOT of students who are just the poorest academic and most unprofessional people I've ever seen (e.g., parties all the time with beer pong FB pictures posted). Even preceptors question how they became pharmacy students. What I found was that most of these "types" of students had connections to the school. Perhaps their parents were alumni that often donated $$$ to the school or some other reason.
So just maybe one can "buy" their way into school, although for unethical reasons, it's probably not disclosed. I suppose it is more common than we think.
