I am in the fortunate position of being accepted to my top-choice school, which I will refer to as school "A," with great funding. One of my advisers (a Graduate Student Services Coordinator at my undergraduate institution, school "B") is, however, encouraging me to try and "negotiate" for a slightly better offer (i.e., an extra summer of funding). I feel a bit uncomfortable taking her advise. I don't know how, or to whom, I would broach this topic. She insists it is very common; she deals with this sort of stuff regularly at school "B." I'm not sure, though, if this is also the case at school "A." Their offer is already quite generous. I don't want them to think I am ungracious by asking for more money. At the same time, if this kind of negotiating process is truly the norm, I don't want to sell myself short just out of timidity. Does anyone have any advise here?
