I've been accepted to a great Epidemiology PhD program with full funding (program A), and would be 100% happy to go there. However, I am currently waitlisted at a place (program B ) that is a much much better fit for what I want to do, and I would rather go there if I get off the waitlist. My getting off the waitlist is contingent on my POI getting some grants, and not on someone responding to an offer, so there is no clear timeline for when I should expect to hear back.
If I don't hear back by April 15th, I definitely want to accept the offer from program A, and program B knows that I would like to hear back on my final status by April 15. My question is: what if funding goes through from Program B after April 15th, when I've already accepted Program A's offer? I COMPLETELY understand that is not an ideal case and disrespectful to Program A, but I really really think Program B will help me in my career and is a better fit for my research interest, and I will just be happier there for the next 4 years. What would you guys recommend in case this happens? Stressing out about this way too much. Thanks for the responses!
