It ultimately just means that you have to put in more legwork for match planning and backup plans, because you won't get that support from your school.
Realistically, you shouldn't need the school to tell you when deadlines are for for the match. This is your future. You need to take ownership of it. Its true, a lot of MD schools go out of their way to make the logistics of the match as easy as possible, but for those of us that went to DO schools or MD schools that didn't do that, we have to figure that stuff out on our own.
If you are coming up on applying, the NRMP website (as well as AOA website for that matter) and ERAS should be your best friend. You should be hanging out on the
Match Timeline page, hitting up the
Match Registration page, checking out the
SOAP page, and in general know the ins and outs of the applying, ranking, and matching process. Knowing this stuff is especially important for DOs, because we are already at a disadvantage when it comes to matching.
