I did ATPL H CAA exms last year and I found most of the questions to be irrelevant for helicopters.
Most questions are for for fixed wing aircraft.
I almost failed Human performance because out of 28 questions four questions were asking about cosmic radiation and when should I record time flown above 40000 feet for cosmic radiation purposes!!! F...ing stupid questions, f....ing stupid system, f...ing burocrats make me very angry!!!!!!!!!!!!!!!
Anyway I'm still flying with my FAA license in Africa, my jar license so far has just been an expense.
