3.8 GPA at WUSTL in the sciences would be very difficult to maintain. The thing about grades, especially at this school, is that they are not a measure of achievement per se but rather an ordinal metric showing how well you did compared to the rest of the class in a competition for doing well on the exams. I know for me personally, I did quite well there my first semester but the overwhelming homophobia of my peers made it difficult to find study group partners for my science courses and my increasing social isolation affected my GPA significantly. It's sort of like sports, there's a performance you're expected to maintain and all sorts of irrelevant social things will end up having a huge effect on how well you do. Things really went south after I came out but that's another story entirely. I did get a 35 on my MCAT and felt bad about it? I guess that's what they condition you to feel like at this place, lol.
