Yea, that is definitely another reason I'm excited to be attending. I, sadly, don't know the average board score. I will ask one of my friends if they know.
I feel like applying for residencies from DO school is going to be similar across the board. When applying for MD residencies, I don't think they will know much difference between DO schools, they're mostly going to see that you have a DO. Of course, more established DO schools have been sending students to these residencies for longer, so they know the schools' names, but I don't think going to a new school will put me at a HUGE disadvantage. If I work hard enough and do well on boards, I think I will match into what I want to.
Also, I'm from the Midwest, and people around here already know about the newer medical school in Indiana. When the time comes, there will definitely be recognition of the school. Also, 3 other classes will have matched before the class I will be in, so hopefully most things will be sorted out.
Overall, I was scared of going to a newer school, but I turned down acceptances to older, established schools for MU-COM. I have confidence that this school will be successful.
At the end of the day, though, you should go where you feel comfortable. It is a huge decision, and you have to remember that you can give your efforts to whatever school you want to. It should be where you feel happy and supported.
