It was tough. There were several E&M coding audits, so make sure that you know and understand the 95' and 97' guidelines. Bring a coding tool that you are familiar with and use regularly. Someone had said to laminate it and use erasable marker and bring something to clean it with after each use. I didn't do this, just brought several copies of the one I use. They do want you to turn these sheets in with the test when you are finished. Also a lot of long Op notes, I suggest that you look at the answers first and then figure out which one best fits the procedure described. There were no short easy questions. Just watch your time and plow through. I actually finished 2 hours early. I thought about going back through and checking my answers, but when I do that I always second guess myself, so I decided not to and left. Trust that you know the info and don't second guess yourself.
Good Luck to You!!!
