1)Are graduate school stipends always taxed? (or does this for some reason, depend on the school?)
2)For schools that guarantee funding for, say, 5 years, if you need longer than five years, and "lose your funding," does that mean you pay tuition (hopefully just for research credits if it's already your 6th year in school!!) and dont get a stipend? or does that mean you just don't get your stipend?
3) if you are fully funded as a TA, does that typically mean you TA every semester? for one class? (whats considered full time TA)
