Update: I received a TA position offer from GW. With this offer, coupled with the fellowship, the cost of attending GW will become significantly less than at Rutgers. This has put me in a more difficult situation right now to choose between the 2 programs. Also, I don't really know if being a TA is a good idea, I'm worried that the work pertaining to teaching will be overwhelming and could distract me from my studies. After all, I'm joining grad school to learn first. I would appreciate any advice.
