I figured I might as well use the new material.. actually as of Aug 07 the new exam is now being used for Step 2 CK, including media questions. Upto 10 questions will have media content, and I think only the 2008 orientation materials has sample questions for that..
As for CS I do not know anything about the Orientation Materials but if you want I will give you some tips when the time comes, let me know..
