I sympathise with you FOU. For most of their working existence, the nameless persons who set the written exams have justified their positions by writing and rewriting the exams so that the answers are never the same. Heaven forbid we should have the same situation as in the USA, where the answers are published for everyone to see. Go figure! The exams are more complex than the aircraft. So every would-be Aussie pilot has to work out how to think like the people writing the questions, then dutifully forget all the crap after passing and resort to knowing what to do when the oil pressure and oil temperature gauges are both reading high and whether to fly under the eastern side of a CB.
An index? You're kidding right? That would imply some sort of organisation and some knowledge of a good word processing software.
