Soooo i deferred my acceptance last year because of funding and i talked with the department a lot. SUPER nice and helpful people but basically unable to give me too much detail. What the GA/TA ship thing means is basically that some of their students are funded while others are not. In my case last year they were able to fund 3/5 of us. Those three were fully funded along with stipend and me and the other person would not be able to receive any funding through the program. The woman that i spoke with told me i might possibly get money through TA ships in other departments other than creative writing, but basically that i was not guaranteed and that i would have to search for my own TAships each semester. These also would likely not cover my entire tuition. Hopefully that info helps - I was told so much information last winter that i hope im making sense lol
