So I've received all of my grad school offers and it is time to make a decision. Of the four schools that I am seriously considering, two of them are offering much higher financial assistance which includes tuition and no TA duties (both schools in the states). The other two schools (Canadian) are offering a lot less money which also does not include tuition and includes TA duties. If I average out the costs over a year, and assume 2k a year for summer months, the school which I want to go to for its program among other things (let's call it school A), is offering only about 73% of what I could get at the two US schools, but this also includes working as a TA. It is also about 5-10% less than the other Canadian school. I was wondering if anyone has negotiated or has heard of people negotiating financial assistance with graduate schools on the basis of offers received at other schools? Additionally, I have applied for a fellowship, and will hear back from it in the coming month or so. The thing is, at school A, if I get the 17k fellowship, I'll only get 2k additional funding (10k goes to the school, 5k to the supervisor, 2k to me). I feel that if I got this fellowship, it may give me a bit more leverage in trying to get more assistance. What do you guys think?
