So I just called today and they said that not all awards have been given out yet because it is pending on how much money they get, but most of them have been given out - hence our getting our packages before submitting the supplemental app. The info it asks about is for awarding any more funds they get.
You can also waive the health insurance fee if you have your own insurance.
And you can use PLUS loans to cover the whole cost of attendance. They also go away with the public service forgiveness program. They will send us info when the time gets closer. And for people new to getting loans, the entrance interview and MPN aren't required for being awarded aid - they are needed to receive the aid. So you can wait a few months to fill those out.
I didn't see the whole fin aid session at the visit day, but the part I was there for wasn't too helpful. It just suggested various loans, pointed to their website to find outside funding, said that they have more governmental funds coming but don't really count on it (sequester!), and again suggested we look at outside funding.
A professor suggested we look at "niche" scholarships, like for research in a specific geographic region, or if you have an uncommon language skill.
Hope this is helpful.
