Considering that they started interviewing in September, it is quite likely that the class is full by now. I think they were planning on filling the class by Christmas holidays. Of course, people decline acceptance offers, even after they paid the $1000 deposits. Even now there are people who will withdraw before classes begin. So, folks will be taken off the waitlist.
Someone at CCOM told me be this in the fall. I don't remember who, but it wasn't very official.
My point is, it doesn't mean much that the class is full. The acceptance list is not totally viable; people will withdraw.
