Though this may sound unqualified coming from a rising second year, I believe that your choices will be limited to most primary care field (maybe with the exception of OB).
Not all osteopathic residencies are easy to get into, and not every DO who scores well on their boards enters an allopathic program. I can tell you for certain that Rad, ENT, Ophtlmo, are extremely competitive period.
Here is an idea, have you taken the USMLE. I know of several friends who scored better on this exam. The USMLE is a well writen exam compared to the COMLEX. Very few ambiguous questions. Again, this is what I heard. I don't take either exam until next June.
Good luck! Take care.
