An excellent post! High time the idea that by having a pre-view of the questions, without actually knowing the subject, was enough,clearly isn't, and by changing the questions without any warning serves to highlight this. When teaching, even English literature, I have suggested some alternative reading simply to accentuate a point, the first question I have been asked is, "Is this going to be in the exam please?" when I suggest that is doubtful I can see they immediatly lose all interest, they are studying to pass exams, NOT to learn a subject.
I happen to know quite a few old hands in CX and I can assure you all that they are well aware of the network ability of PPRuNe and how to render all but your actual knowledge a total waste of time when you reach the interview stage.
Answer: Know your subjects, not just the answers.
