Looks like we will be classmates
I called and was not assigned an advisor yet. I registered for class anyways but as a non-degree student. The graduate engineering office said it would be fine because the credits will just be transferred.
I was living in lower allston, but I am moving to be closer to BU. I got a dorm-like room via graduate housing (http://www.bu.edu/rpm/). It was (very surprisingly) reasonably priced. I got a room for $850 a month with heat/hot water/electric/gas included and it is 5 minutes from the engineering building.
