A supervisor gave me some blunt feedback on my mock exams recently. "You can spot the right answer without knowing anything. It's the long one." He was right. Three short answers and one long, detailed technical one. Guess which was correct. I ran the numbers. On some papers, picking the longest answer every time would have scored 91%. That's a pass without opening a book, and it's useless as preparation for the real thing. So I rewrote them. Over 550 answers across nine papers, every one checked against DWR 1997, the ACOPs and DMAC guidance. The answers are also shuffled every attempt now. Picking the longest answer now gets you between 13% and 29%. The pass mark is 75%. While I was in there I fixed a few things I wasn't happy with either: out-of-date guidance, a question with two right answers, and some regulation references that didn't match the actual wording. If you're sitting your Air or Bell supervisor exam, the only way through these now is to know it. Which is the point.
