I am a third year osteopathic student interested in allopathic anesthesia spots. I just took COMLEX 1 and scored 98th percentile. Some people are telling me that I should still take USMLE, but i really don't see the point in doing so, considering i may not do as well as i did on COMLEX. What would i be trying to prove by taking USMLE? Any input is appreciated.
I am a 4th year DO student applying to MD anesthesia programs this year. From my experience (which is really only limited to cruising SDN

), MD programs like you to take the USMLE as a way to compare you more easily to other applicants. Most programs don't want to go through the mental gymnastics of trying to convert your COMLEX to an approximate USMLE score, considering that there is no truly reliable way to do it.
Not sure how many programs outright refuse to take COMLEX, but I know that while most will accept the scores, they want to see USMLE as well.
I don't think it has much to do with you needing to "prove" anything. One can argue that the USMLE is a superior exam compared to COMLEX, which I felt to be more true of step 2 rather than step 1, but that's a different subject.
I would recommend that you DO take it if you still have time and think you can do just as well/better on it. Even if you have to put it off a little into your MS3 year, I think you will be glad that you did come application season.
