One point that people seem to dismiss is that DO schools in general aren't that supportive of their students specializing. Osteopathic medical schools have unspoken obligation to send certain % of the student body to primary care (more like a requirement that needed to be met for the school to open in the first place, get support, funding, etc). In other words, DO schools don't give a flying crap if the student's dreams of specializing are shattered due to low board scores or whatever reason. All they care about is the % matching into ANY field of residency so they can boast 98% match rate blah blah. In fact, some DO schools even seem to gear students toward primary care by taking away student's time to study for the board (I'm not saying primary care sucks, I'm just saying that every student has different interest in mind, and school should at least leave them alone to try their best to land that residency of interest, rather than being a hindrance).
That's why some DO schools go as far as accepting people with MCAT ~25, because they know these students will likely match SOMEWHERE eventually. This should stop for the sake of DO school's future. It's hard to deny the correlation between MCAT and Step 1, and accepting students with lower credentials will continue to foster students with lower board scores. Also, what frustrates me with DO schools is that they put way too much emphasis on OMM. Sure, the students agreed to pursue the osteopathic philosophy, but little did we know it would take up a bulk of our board prep time. Some premeds may think, "oh it's just one more class, not a big deal.." but on top of all the rigorous classwork, one additional class + lab for all 4 semesters makes a lot of difference. As much as I respect AT Still and all his work, it pisses me off to see myself spending way too much time in OMM while my MD counterparts are underlining First Aid. On top of this, DO schools in general give less time to study for Step 1 at the end of 2nd year. Most DO schools give ~ 4 weeks (worst was CCOM with 2 weeks...seriously, that's not even funny) while MD schools give 6~8 weeks.
The point I'm getting at is that DO schools are less concerned about their students excelling in board, and they could care less about a student's dreams of specializing being shattered. If any premeds out there plan on going DO route, just be aware of these obstacles in the process of achieving high board score, and be ready to work extra harder. Yes, there will be discrimination, but it can be overcome if your mind and soul are set in killing the board.
