I'm in the same boat of having not heard back. I am planning to call today as MCG is only conducting interviews through December this year and only 2 days a week. I went to the same university for undergrad and have a LM of 72. I really thought I would have heard back by now since I was complete by September 1. I also got the email about sending in tax forms even though I had already submitted them. I usually wouldn't call, but I just want to make sure I didn't mess anything up.
