About 6 months ago. I have to pass a written as well as a practical exam annually to keep my job. And you can't pretend.
Don't be silly. I can't believe that either you or MH are that dense. So you know what I mean, you're just pretending that you don't. So you can pretend! Of course, this isn't an exam.
That said, I don't believe there were actual exams in the examples I mentioned. Just attendance and general agreement of the principles. I was led to believe that the way to advance was to nod sagely and not rock the boat.
