I turned up to mine early (as i do everywhere).
I walked in to the building and the old geezer who was the moderator came out and said
"why are you here?"
"I'm here for the AM2 sir"
"Your half an hour early, that's not very good is it, if you can't even turn up at the right time how am i supposed to have confidence you can pass the exam, now go away and don't come back till 9.00am"
Turned back up at 9am, another lad walks in at 9.01.....
"your late, whats your problem, you can't even turn up on time for an exam......
and that's how the day proceeded! IIRC we all messed up some part of the safe isolation procedure as everyone was papping themselves!
