"I'm sure most airline pilots would struggle to answer some of those questions ...."
LOL! This is from one of my students:
Bumped into an ex Cathay Dragon guy at Skyborne while doing exams (lot of crews back in the U.K. and having to convert HK licenses). Long story short having kept in touch, two current A330 crew failed multiple exams in the first batch they sat from QB2020 and they have nothing else to do apart from study.
