It's called Holy Cross (Junior) College, and I knew of a few folks who transferred in to complete their bachelors degrees. And they DID complete their degrees.
What I have never understood is why ND hasn't turned Holy Cross into a feeder program for kids who want to play for the Irish but can't make grades out of the gate. Let them study at Holy Cross, play good ball, and figure out how to make it work. Then transfer in when they're ready.
