Oh, and here are the correlations from the above post:
Step2CK = 1.67*UWorld + 125.95 R2 = 0.67
Step2CK = 0.65*UWSA + 83.25 R2 = 0.50
Step2CK = 0.60*NBME + 102.01 R2 = 0.53
To access the images, I had to click the attachment and then click the center of the black image that displayed. Sorta odd -- maybe it's a .png issue. Good luck all!
