Just a heads up, I got a call from Michigan's MPH program (I believe it was a faculty member) just asking if I had any questions about the program and asking really basic questions about me (where I live, what work I'm doing, what research interests I have, what professors work I'm interested in.) If you've applied/been accepted to Michigan, maybe just have a list of questions for them saved in a note on your phone. They gave me no head's up so I was completely unprepared and couldn't think of any questions (and was still in bed

). It didn't seem too serious (I hope not at least) but it would be more productive if you can actually think of questions you have!
