interested in IM/cardiology at University of Maryland but am curious if I need to take the USMLE on top of COMLEX?

From what I hear a lot of hospitals take COMLEX these days but I wanted to see if anyone knew around here before I buy books or other stuff.

You need to to take the USMLE step I and II for IM at the university of maryland.
