    U world percentile correlation formula.

    Want to try to gauge if this formula works for predicting possible outcome in step 2 ck (since I feel NBME was a weak sauce predictor of my performance.

    ((Uworld second pass percentile-Uworld first pass percentile)/4)+ uworld first pass percentile= real ck percentile

    For me this formula was spot on: (58 percentile- 22 percentile/4)+ 22 percentile= 31 percentile on the real thing

    What about other people, does this formula hold up?
