there is great importance with associated with the usmle and correctly so. however a given sore form one school may give you a better chance than from another. this is hardly absolute, but do take a look at placements between each school. Also, and this is down the road for you, but a huge factor in getting a residency you want? Apply to ERAS EARLY (that's the application program). Two candidates who apply on day one versus midle of the season in eras will have possibly great differences in outcome all other things being equal.
