My dad talked to one of the guys who works for my congressman. He said he called the admissions people and they said I probably won't hear anything for about a week. Will the wait ever end!?
I am in the same situation. I don't think you need to call them. They just haven't decided to give you an appointment/TWE yet. I think it is good, though, that you made it past yesterday. A TWE is probably on the way.
