I think there are a few 5 year undergrad/medical degrees or used to be. Jefferson had one in PA and Canada had 6 spots per year in certain schools. Know of a few people who did them in Canada and Jeff.
But you have to be really outstanding to get in.
My BIL declined to do the Jefferson program because too many of the students were clearly in it for the money. I think he just didn't like Penn State.
It's Penn State's baby.

I would expect that parents on this forum would have kids who could do this.
You can also apparently apply to the Penn State Medical School after two years at Penn State. I did not know this.
