No worries
Hi,
I've succeeded in French Air force tests and i was student fighter pilot, some other didn't, and they made a better carrier as civilian pilots.
I've passed all my commercial exams at first try, some didn't, and they succeeded in the same kind of assessment you failed and i failed too.
I've always been rated among firsts in all the flight test i've passed, i'm still struggling after many years on that business, some people went straight away to big airlines jut by knowing the right people.
An airline offered me a job as direct entry captain on JAR 25 aircraft, another said my English was too poor to make scheduled flights in France even as a copilot (from a French airline it's really insulting, but they tell you that in French),...
You'll see by yourself such assessment have nothing to do with real capabilities, i know people you wouldn't dare to lend them your bicycle, they are in Air France now, other are in Net Jets and so on.
If you find hard the training you follow, that's normal, and it's not finished.
For some people it comes fast, for others it takes more time, and at the end, the one who get the job is more the one who is "assessment and network specialised" than the one who's the best at flying.
Do what you feel, don't be depressed for one assessment failed, and keep in mind that all this stuff is show business, mostly organised by "human resources specialists" who don't know anything about flying, but who have to sell themselves in order to keep their own jobs.
Hang on.
JC.
