Don't worry about the A levels (too much!!). They're part of th requirement to show that you have the aptitude to do the bookwork required when you start at the college of ATC.
If you want to do it, apply and you'l have to go and do some selection procedures which ARE important as these are what NATS deems to be the best yardstick for potential students. Just call personnel and get an application form and we'll see you on the radars very soon...
