"It's more honest to read the books.......?" - Is this guy for real?? Does the CAA/JAA - whoever really care if you're 'honest' about studying and not doing the feedback for the exams......I don't think so. They're not as honest when charging an arm and a leg for the exams (but thats besides the point). Without taking a personal dig at you - I think we know exactly how 'honest' YOU, I or ANYONE ELSE on this (or any other forum) will be when doing the exams. Bottom line - everyone will do whatever they can to get away with as much as they can - if if using feedback is 'getting away with it' then my naive friend good luck to you.
Now if you're talking about understanding the matter - then that's a different story.
