I guess no one studies the syllabus material these days. Just a matter of memorising the answers to pass the exam!
The result of this is very evident here on pprune. Lots of people asking questions. Lots of incorrect answers forthcoming.
No one seems to know where to find the correct information. Because they've never bothered in the past.
Too lazy to look it up. Don't actually have any documents to look up. There're too expensive to buy and maintain!
As a group of so-called professionals, we really are dumbing ourselves down! And a large part of the industry is taking advantage of that.
