I've never really gotten a decent answer to this question, and maybe that's my fault. I know that the DO match is before the MD (a month or so?). If you are applying in both matches, and match DO, you have to go DO. Am I okay so far? DO can then match into a traditional internship, or a specialty track residency, or whatever. Here's where I get a little fuzzy. If you wanted to match into a DO general surgery program (this is an example BTW) do you have to first apply to a traditional internship? And then the next year, apply for a PGY-2 position? In other words, do you have to, in effect, apply in two matches? In any case, if I've got something wrong, please correct me. And if you have answers to the questions I have, I thank you in advance.
