Hi Dirk,
Excellent description of this test!
Truly it reflects what happens in the SIM.
I'm in the same situation as you, so I know how you feel!
I have 200hrs and felt like if I just could make just a bit more perhaps I could do it, but perhaps more and more I feel that I never had a chance. At least with my little experience.
I just think they just push you so hard that it's so difficult for a low houred to pass this kind of exam. I think, even for people with some hundred hours, this would be an extremely difficult task.
If it is like so, why do they open this to 200hrs? Why don't they just open to 1000hrs with jet experience like everyone else?
Bit disappointing though!
Good luck!
