Someone correct me if this is no longer the case, but as I have been informed:
At Georgetown, grading operates on a curve. Only so many people can get honors. This is the epitome of what medical schools are trying to get as far away as possible from. Furthermore, there are hundreds of masters program students that are in each of your M1/M2 classes. Not only is this logistically irritating (not to sound 'above' them, but it would be nice to not have hundreds of people not in your med class in your classes, right?), but they are desperate to get into medical school in a succeed-or-die situation, and they are graded against how you do in the class. Recapping, nobody- from the grade-desperate masters students who clog up your lecture halls, to your 'real' classmates, has an incentive to help you, making georgetown the school with the system least fostering of collaboration. Sounds like a great time
