I like how you think, zb. Please see my comments on grades at Hopkins under "Impressions of Hopkins". Now all systems are not right for all people, but I think there's some truth to the notion that you WILL slack if you are ALLOWED to slack... I know I would. And I know I don't want to be a slack doctor.
That being said, I worked with a surgery intern from Yale med school last year, and he was great. I asked him how the Yale system could possibly work, and I honestly can't recall what his reply, but I guess it didn't make a huge impression, or it wasn't convincing.
Wherever you go, you will get out of your education what you put into it. Being at a big name school does not guarantee you'll be a great doctor. Studying hard and learning the material well is still no guarantee, because you also need common sense and clinical sense.
Good luck to everyone.
