I got 68% correct on UWorld (the website says that's a 240) and got a 252 on my real thing. You have to be careful with these b/c sometimes people start the question bank w/o much base knowledge and simply use the question bank as a learning tool (i.e., to extract the information and learn), while others use it was a performance assessment after they've gone through the material in much more detail than many people. Then you have people in between. I wouldn't look too much into correlations btw UWorld correct and Step 1 scores, unless of course your % correct is off the charts and you use it as a confidence booster.
