I am having the same dilemma! The tuition at both schools are very similar and not a decision maker in my mind. Without a doubt, Marquette has some of the nicest facilities I've seen at any dental school and I truly felt at home there. On the other hand, Chicago is where I want to be and where I'd like to practice in the future which is what is deterring me from Marquette at the moment. Any other advice on how to make this decision??
