Without wanting to pee on anybodys bonfire, back in 1999 I ended up sharing a doorstep outside BAE Prestwick whilst FCL CAA Chappie was having a smoke, exams were well under way inside.
Quote was that remarking exam papers is a bit of a cashcow for th CAA, the machines are that accurate its either correct or a spoilt paper sort of situation.
No doubt somebody out there has had a remark and passed, if so well done what were the circumstances?
