I interviewed at MCW and loved it. The students at the school were really laid back. The facilities were really nice. And I believe that MCW is ranked higher than Penn State. I'm stuck between schools too. It is a hard choice to make. I guess you have to look at all factors. The only thing I didn't like about MCW, honestly, is that it is just a medical school and there is no undergraduate campus to give a sense of college life. But other than that, it was an awesome school.
Good Luck
