Hi Arshia,
Same here. I have been accepted to Columbia's MSAUD as well as the MUD at Taubman, Michigan (with a slight scholarship). It's certainly a difficult decision. Columbia is appealing despite its high cost. NYC certainly plays a big part in the decision making, especially considering employment opportunities and the like. I'd really like to get a sense of the employment opportunities for alumni from both schools.
Another factor is the class size. I think the MUD at Michigan has 7-8 students. I'm not sure about the MSAUD but it may have 50 or so.
Have you made a decision yet? Good luck.
