Hi,
Hope this is posted in the right place...

I have been offered a scholarship at Uni A which covers fees and offers a stipend equivalent to research council level. Obviously, I am pleased but I am still waiting to hear from Uni B where there is a fantastic supervisor that it would be a dream to study with. I shan't hear from Uni B for about two weeks and I have to make a decision on Uni A within the week and I have to sign papers saying that I've accepted. Is it ok for me to accept and, if Uni B comes up with funding, decline Uni A in a couple of weeks?

Ideally, I'd ask Uni B what my chances are but I know that the people I need to talk to are out of the office on leave and aren't due back until after my decision is due at Uni A.

Ethically, I really hate messing people about so I feel awkward and uncomfortable about this but I also know that I need to look out for what's best for me. Any advice would be greatly appreciated.
