I am a graduate of an osteopathic medical school and currently attending an ACGME accredited internal medicine residency. I have taken both Comlex and USMLE for Steps one and two and passed both of them. Would there be any benefit for me to take USMLE step 3 as well as Comlex III? Note: I have taken Comlex PE but have never taken Step 2 CS which I would have to take as well in order to be eligible for USMLE step 3.
