Can somebody tell me something about the CS BS/MS program?

I am interested in that program right now but I don't know much about that. Can somebody say something about that? What you like or you don't like. Or anything you know about that. Do you need to take a lot Grad level classes? Does that influence getting other minors? I am interested in getting a Math or Stat minor. Do you need to a thesis to graduate or taking classes is enough?
