well done dalef,
you've got a great opportunity there mate that many would love to have.
ray's made a valid point, rely on yourself. learn all you can and set your mind on being the absolute best YOU can be. really show a determination to prove you are worth the chance. People will forgive your mistakes if your attitude is right ;o) Weather you are a tiler, a road sweeper or a brain surgeon its all the same, your attitude to do things to the best of your ability is what will make you succeed.
anyway, enough of the motivation spiel, good luck and make this opportunity work for you ;0)
