The best way to think about this is- who cares? People who didn't pass when I was in school were either those who spent too much time texting, at the bar or hosting house parties. They were constantly cramming last minute in the first years and were holding on by a thread. I am not saying these people deserved to fail, just that they probably had it coming. There was one guy who legit failed because he just couldnt get it, he then failed COMLEX 2 first time....and STILL ended up graduating in our class.
These first pass stats mean little to nothing to the individual. Work hard, study from DAY ONE and you'll be fine.
