I have two offers for a physics PhD in the UK. Both are great choices and I don't really have a preference. However, neither is funded so far and on both sides, the PIs are actively looking for funding and I think the chances are very good that I will eventually get it.
Both universities have a deadline for acceptance by the end of the February and the funding situation certainly will not be resolved by then. What do I do? I'm essentially ready to commit to whoever has funding. Should I accept both offers now and withdraw from one later (assuming this is allowed) or should I ask for an extension from both?
