We had some students from Mayo Medical College and they said there is one block worth of questions which are experimental, either in one block or more often dispersed within different blocks. Of course we cannot tell which ones are they but if they seem way too difficult than you can even imagine, just take a guess and go ahead is their advice.
When I took my Kaplan course they said the same thing. The USMLE scoring process is not transparent. They do admit to using experimental questions so there will invariably be some questions on your exam that dont count but you won't know which ones they are and its entirely possible that the USMLE also doesn't at the time your exam is generated, know which ones they are.
Since the process is not transparent the advice is to mark every question to the best of your abilities and after a few minutes if you have no idea whats going on - to quote Dr. Stephen Daugherty from Kaplan - "Mark your favourite letter and move on"
