I did my RAE in Suffolk and the lecturers taught us all on the syllabus, with had distinctions, credits, passes and failures, son did his in North Wales the lecturer said you can pass without knowing this and it's hard, so learn just this and this, no distinctions, no credits, but also no fails, everyone passed. ... Often wondered which was the best.
I suppose it depends upon how you view the issue but, in general, it's usually not too hard to decide which is the better of "learning about all of a subject properly" and "learning how to pass an exam".
Having said that, I suppose it's not necessarily that straightforward, since there will be a wide range of opinions about what aspects of education/training which results in 'qualifying' someone to do do something (e.g. 'vocational' training, or RAEs) is actually relevant to whatever it is one will become 'qualified to do' after passing the exam. Many, perhaps most, of us who have gone through periods of such education probably feel that a fair proportion of what we had to learn (to pass the exams) was 'unnecessary' (but see ** below), in that we have not needed the knowledge in question during our subsequent careers.
Hence, if the lecturer in North Wales was saying that he would not bother to teach things which he didn't feel were relevant to having and using a Radio Amateur's licence, then perhaps he was being sensible. However, I doubt that was the case, and think it much more likely that he was merely teaching 'how to pass the exam' - which is far less laudable!
[** just to be clear, in many/most disciplines, it is (in my opinion)
essential that a good grounding in underlying basic principles precedes learning about 'practically relevant' aspects of the discipline and, at least at the time, a good few students consider that as being boring, maybe 'unnecessary' and, in some cases, 'challenging'. However, as said, I personally regard that as essential, and certainly would not suggest that it should/could be omitted. Indeed, as many subsequently come to realise, that 'grounding in underlying basic principles' will usually make it much easier to understand and lean about the 'application' of those principles to practical issues. ]
