I did COMLEX only, and killed it.
My biggest problem this interview season is going to be how to rank my favorite FM programs, as they have all made it pretty clear that I'm going to get the one that I rank first.
You are so much more than a board score, and that is especially true in Family Med. Get involved. Go to FM conferences. (Shout out FMEC!) Reach out to program directors of your favorite programs. Do audition rotations at your favorite sites. Find out which programs are doing things that interest you most, or that are situated in communities you want to serve, or whatever. Make connections at those residencies that you want and you will have no trouble finding your spot and having them want you just as much as you want them.
