The recent exam I did was very tricky. New questions I've never seen before, and others I just didn't understand even what the question was asking (Chinglish).
Not sure if its some seasonal change, if a new manager has changed lots of questions, or maybe someone up top wants to make it difficult to get foreign Captains to get hired. One thing is for sure, and that is it is a pain the the bum doing this exam.
I went in this exam with a fair degree of confidence after boning up on all the previous questions. I was shocked when I saw the exam, and so many questions that have no relevance to the job but obviously someones picked out many obscure details from manuals charts and aerodynamics. Unfortunately I came just short of a pass. I'll sit one more time after studying all the new info that's floating about.
Best of luck to any others going through the process!
