I have been using a tutor / studying partner from the future mds website to pass the USMLE on my first attempt. There is a section on the web page to view and understand the scoring of the USMLE Step 1, 2 CS and CK. I hope you find this as helpful as I have in my studies. There are also some High Yield Concept PDF downloads for USMLE Step 1 and Step 2 PDF. Good luck with your studies, hopefully this information is helpful.
