I was checking out Western U/COMP's list and noticed that a column states "Title" and under it each residency is classified as either "AOA" or just blank. Does AOA title indicate that it's a DO run residency (meaning you don't need to take the USMLE) while blank ones indicate an MD residency (meaning USMLE is neede)?
I would plan on taking the USMLE if you are applying for allopathic programs. I have had correspondence with allopathic institutions and programs that have notified me that they do consider "COMPLEX" scores. That right there tells me that I should try to provide them with an exam score they are familiar with.
