Hmm, i dont remember the data but is the total number of applicants (including all IMGs) lower than the total number of FM spots?
There are no specialties for which there are more spots than the total number of applicants.
A number of applicants seem to believe that IM is more achievable than FM because there are so many more IM programs, so you can apply to a larger number of programs and thus are more likely to find one to bite. There is also a higher percentage of successful IMG matches in IM compared to FM. However, I (and many others) think that this is simply a misconception that FM is "more competitive" when in actuality:
1) The ratio of applicants:spots is actually lower for FM compared to IM (ie yes there are more IM spots, but there are also more people you're competing against)
2) The average successful IM applicant is more competitive than the average successful FM applicant
As you can see from the interactive chart, the match percentage for someone with the OP's stats is similar between IM and FM, but FM is much more forgiving for applicants with a step 1 in the 210s and even 200s. So for applicants with low scores who aren't getting bites from IM, trying FM instead makes sense.
Unfortunately, the fact that the OP isn't getting bites with a step 1 score that would be expected to succeed makes me think one of 3 things is at play here:
1) The YOG really is 2010 (if that's the case, I don't think there's much that CAN be done)
2) The CS failure is really dragging him/her down, and/or hasn't been rectified
3) There's some other red flag that we don't know about.
Interestingly, when I impute a PhD into the chart, the match percentage goes from 70% to 0% in the OP's score range (0/5 applicants with USMLE 210-230 matched over the last 5 years), making me think there's likely something else holding these applicants back. FWIW, there's only been one MD/PhD applicant in the 220s to FM in the last 5 years, and that person matched. In any event, regardless of whatever's going on, I'm afraid he's getting a clear signal that IM programs are not interested and he should change strategies.
