did maths, physics, geog and chem but the a levels aren't the important thing, as long as you have the right credentials (3 A-C a-levels, good gcse's and possibly a degree) then you shouldn't have too much trouble passing stage 1.
Stage 2 is a really straightforward maths test followed by a couple of tricky aptitude tests.
Stage 3 is the real test, yesterday was a battle of nerves and remembering all the research i had done on the company and its partner airlines. Even as someone who has hardly any flying experience, to be asked "If you were CEO of Monach, what issues would you address based on current aviation affairs?" makes you blummin' glad you were prepared!! Oh and most importantly make them know you really want the job!
But hey i still have stage 4 to go so i'm by no means home yet!
