Again, not saying that WashU gives out Hs to everyone, but you kind of made my point. WashU and its hospitals are known. You're comparing a known hospital for an unknown one, and claiming that surely the rotation you know nothing about is easier to get an H in than the one you know about. The truth is you can't know that. You don't know anything about how students are graded there or how difficult the attendings want to be there. Now if you compare students on the same rotation at the same hospital, you can objectively compare the difficulty of grading on their rotations (within reason - there are still unknowns), but again your initial point isn't accurate. Again, PDs will say that the WashU kid with an H in IM is better than the Meharry kid with the H in IM, but its not because the WashU kid definitely worked harder to get the H, its because he's from WashU, a program that is well known and established in the field.
Honestly, I feel like I've beaten the point, which was not all that important to me, to death. So yeah, that's all I care to say about it.
Moving on...
