They shouldnt place too much on academic prowess I think... The guys & gals interviewing us will be pilots themselves and they'll be asking themselves if they'd want to spend hours in a cockpit talking to your boring ass.
I'd imagine they'd want to see committment to something/anything and an ability to think under pressure. Might also help if you like the smell of kerosene...
It's their course and they can do what they like. Unfortunately i am shy on the A-level department.
Serves me right for having so much fun when i was younger i guess.
