It's really hard to say what a competitive step 1 score is. I think that it all depends on the program that you're looking at...but then again some programs don't give interviews to people with extremely high Step 1 scores. Although it's hard to say, I'd say that a step 1 score above 225 would help make you competitive at any program... On a different note, I know people who scored below the mean on Step 1 and still matched in EM...If you have a program that you like, go rotate there...my unofficial feeling is that letters of rec, clinical factors mean a lot more...just my 2 cents
