Since this same question was posted by the same person in IM, EM, and Neurology, I will answer in all three. You dont have a chance at Neurology and EM. If it were just your board score, maybe....but you are in the bottom quartile of your class, you are an osteopath (which unfortunately, means getting an allopathic residency is intrinsically more difficult), and your board score is low. Furthermore, your dedication to EM, IM, and Neurology is in question as you cannot commit to any of them as a calling. I would strongly suggest looking into community based programs for Psych, Peds, FM, and IM.
