We're still trying to get more data for the Step 2 estimator. Right now it is not all that accurate (which is why we didn't include a Prediction Interval). Please ask any of your 4th years or interns to submit their step 2 scores to this site.
We're getting pretty good submission rates for the Step 1 estimator. Please continue to bug your 3rd years!
Hopefully this site will be of some help to people as we enter the Step 1 season...
