Hi Pilotho
Like the lads say above the assesment is lost and won in the sim from my experience.
If You fly well, wipe the Pilot monitorings backside
and be yourself you shouldnt have a problem.
They want to see could they stick sitting beside you for 8hrs a day.
I dont know how many questions i got wrong although they were in the minority, i still passed.
Its a great experience anyway.
Good luck
