Since I am a graduate student I have something to offer here. My program is medical physics and is offered in the school of medicine at my university. I think the whole getting lower than a B thing (at my school a B- is a fail) was implemented because at the graduate level they expect you to not only understand the material, but also apply it. Getting lower than a B probably demonstrates that you were not able to do this. Many of my professors WILL NOT HESITATE to give out a C or D or even a B- if you do not understand the material or do the work, but the reason this is unlikely is because our program directors make sure that all we have to do is study. Most everyone commits themselves to the program, and don't work unless it is TA or research related. I personally busted my ass last quarter to get my A's, it was a lot of work. So for all you guys who think a masters is a way to show off a high GPA, I would think twice. Of course I can't speak for all graduate programs, I am sure some are not that tough to get a good GPA in. But I am sure the adcoms will know differences in quality with regards to grad programs. Another thought,99% of those who go to medical school pass all their classes and get their MD. That doesn't mean that no one busts their ass in medical school, so eqauting grades and passing stats with difficulty isn't fair in my opinion.
