Case western and Nebraska are the only two... the amount on medical school you have to take depends on the medical school administration. I didnt apply to Case, but did interview at Nebraska's program. I thought it was an excellent program. I ranked my program ahead of it based on the training experience, rather than taking one less year. In my opinion, it is not worth sacrificing training for one less year or the lure of a resident stipend while in med school. The 5 year programs and the programs which pay you all 6 years are popular and competetive. Some offer great training, while others are mediocre. You only get to train once, and learning thru CE courses is expensive and difficult.
