I received my acceptance email for MA in Literary Studies yesterday evening, so it could be that Purdue is sending out another wave of acceptance letters.
I was also offered a fully-funded TAship during my two years of MA, and (as long as I remain in good standing) a guaranteed TAship for the next five years while I work on my PhD.
Thank you ComeBackZinc for the info about the Lafayette area. It will be very helpful in making a decision!
