There's one thing which I've never quite undersood- why are JAA exams formatted with multiple choice questions, rather than, as is the norm in Higher Education, on the basis of questions which require a student to definitely know the answers.
It's akin to "Who wants to be a Millionaire?", as opposed to "Mastermind"! The WwtbaM route gives a four in one choice, even if the correct answer is not known. It also leads to the present thread, which surely is advocating to potential exam candidates "Let's look at the answers to the questions before we go in"
