Oh dear! A rather tongue in cheek comment rather seems to have upset you. For sure I was happy to pass, and if 80% was not OK, then the pass mark would NOT have been set at 75%, would it??. For your information, I was rather disappointed at my pass mark, 'cos in the mocks I got just under and well over 90%. Also I was pissed off with myself for changing two answers from right to wrong, which would have made it 85%. I have worked bloody hard at this exam, something I have not had to do for nearly 45 years.
So, as I said, a pass is a pass, and afterwards I had chance to see where I went wrong (which included a couple of silly mistakes, but I am only human), so please, get off your "Holier than thou", attitude and keep you mind on your own abilities
