Umm, I just installed the USMLE Orientation CD for Step2 CK. In the tutorial section, there is a page where you adjust your audio. Uhhh, is there audio on this exam??? Any recent test takers?
And from that link:
A small number of multiple-choice items with associated audio and/or video clips will be introduced into the USMLE Step 2 CK Examination beginning in early August 2007. No more than 5 items with associated media clips will appear in a single examination. The 2007 USMLE Orientation Materials include a small number of multiple-choice items that contain exhibits involving audio and/or video clips. Instructions for practicing with items with associated media clips on Step 1, Step 2 CK, and Step 3 are provided in the Tutorials for each Step examination in the orientation materials.
Items with associated media will be introduced in Step 1 and Step 3 during 2008. An announcement will be posted to the USMLE website approximately 2 months before any items with associated media clips appear on Step 1 or Step 3 examinations. Additional information will be posted to the USMLE website as it becomes available.
hmm I think this will actually make it harder. I'd rather be told its a machinery murmur rather than having to listen and figure out what I'm hearing. Glad I'm writing before the new exam starts. Although, chances are, all of the audio questions will be experimental so who really cares I suppose.
