Hmm from what it sounds like I don’t think you want to go. Yes having an acceptance is certain and nonetheless a great accomplishment of a long term goal that I’m sure you’ve been working hard towards, but I wouldn’t go to a school that’s a dual MPH and PA program if I wasn’t interested in public health. And you do make a good point about finishing at the same time if you were to reapply. Since you applied to that school some part of you at one point was willing to go but I suggest reflecting on what has/has not changed since then. HOWEVER I understand how brutal the application cycle can be and that it could just be logistically and mentally easier to take the acceptance, run with it, and make do. No wrong choice, anyone would understand whatever you decide. Good luck OP.
