gibbo1305,
I tried for work experience when I was 14 at Swanwick and didn't get it coz I screwed up the interview!
I am 16 and have passed all my GCSEs and onto A levels now but as other people have said, I don't need good grades as I can apply anyway as long as I have studied to A level examination.
Definetly apply I will be when I am 18 and can't wait!
