I just found out from some other students who were registering for classes that, contrary to what I thought was a totally free and clear grad program where they actually paid me as a grad assistant and I just spent my time studying, teaching and doing research, THIS PROGRAM IS NOT FREE. Au contraire: we don't owe tuition, but we do owe what they're calling "fees." Mine come out to $685.00
They didn't tell us this, and naturally I didn't factor this number into anything, so it looks like I'm spending a bit more of my savings than I had previously thought to go to grad school. I might cry.
