Experimental questions in Exams?

[teamforce]

There are 15 "tryout" or experimental questions administered with each exam. Once these questions are thoroughly tested and analyzed, they may become "real" questions in future exams.  So don't be overly-alarmed if some questions appear to be very strange or out of the ordinary.

An exam wth minimum of 75 questions will have 60 "real" questions and 15 "tryouts". For the 265-question exam, there are 250 "real" questions and 15 "tryouts".

I hadn't heard of this.  Are they clearly denoted so that you aren't stressing to answer questions that aren't genuine?  I'm assuming if they are not "real" questions then they would not count in the grading of the test.  I get enough anxiety from test taking that I don't think it would be fair to include questions that didn't count without making that clear or optional.  Now I'm going to have to do some research on this to find out more.  Would you be able to post the link to where you read this information?  Or did you have another source offline?
