Was anyone here at the Open House? I met a few students there and have been in regular contact with them since, they've all been very helpful. A couple things I learned (also not on paper, but just from hearsay):
1. I've heard between 130 and 200 people apply every year, and they make about 50 offers to end up with a class size of about 40-45.
2. Vast majority (nearly everybody) ends up with an RA position, though you should expect to compromise on specifically what you want to do research on in order to find a supervisor.
3. RA funding is significant enough that it covers all tuition, and you end up with about $2200 per month leftover for housing, food, etc.
Where does it say that the application deadline has been extended?
