A lot of people mature substantially between their undergraduate years and graduate programs - especially if they don’t go straight from one to the other. I was drunk more or less permanently from 1999 to 2003 while I was an undergrad and pretty much just went to campus to get the syllabus and for midterms/finals, except when I had a hankering for Steak Escape (the only one in town was in the Student Union) and incidentally went to class afterwards. I had something like a 1.9 GPA after two years of my BA program and finished with a 2.5. It wasn’t like I had other onerous obligations, either; I was in a fraternity and I had a part-time job just for extra drinking money, and that was pretty much it.
In law school, by contrast, I only missed about 5 classes in 4 years and graduated cum laude - working full-time and going to school at night.
I mean that if she was going to die, she was going to die whether or not 95% of similar patients do. I’m not saying I agree with her analysis.
I’m only familiar with the Australian system, but the people I know who’ve worked in both systems tell me that the graduates are the same.
You have to be exceptionally good at studying / learning. The system (in Australia) is set up to help you: they know that you have to learn a lot of stuff, and they try to make that possible. But you have to be good at studying / learning to get there, you have to be good at studying / learning to get through, and you learn a lot of good studying / learning skills as you go.
The medical students weren’t exceptionally smart (the exceptionally smart students were in physics, not medicine). The course work was exceptionally well explained and taught, so they didn’t have to do any more thinking after pre-med. It was clearly easier than engineering. Except that there was a lot of it. A truck-load of content. I heard about physics students that were smarter than their professors, but I never heard of a med student who knew more than their professors.
