The problem here is not the OP, it's the way admissions are set up. DO schools do not have a set date like MD schools do, so there is
nothing wrong with holding two acceptances. Applying to medical school is always going to be stressful, but I have to believe there is a better way to do it than this. Dragging this process out for an entire year is what leads to situations like these. I wish they would compact the season so all waitlist movement would be done by now and you wouldn't have the situation where you're expected to move across the country and start class tomorrow. I suspect it's a ploy to get more money from waitlisted applicants who are reapplying
(sort of kidding).
Yes, it sucks to those people still waiting but you need to look out for your interests first in this process. Of course you want to try to be considerate and do everything you can to make a decision as soon as possible, but if you are truly undecided or have extenuating circumstances take the time you need to make sure you're making the right call for you.
It's a little unfair to judge without knowing the exact circumstances of this decision. As some others mentioned perhaps he just found out he was accepted off a waitlist and was inquiring on how much time he had to decide between the two schools. Many people have family, spouses or significant others to consider in their decision too. I'm currently holding 2 acceptances for this reason (1MD, 1DO), and while I do feel a little guilty about it, it's what makes the most sense for my situation right now. I know it sucks being on the waitlist, Im currently there at my top choice school, but that's just the way things work unfortunately....hate the game, not the player, no?
