Got to agree with the posters above. Im at uni myself, got a year to go. Aim to graduate in the summer and start ATPL's as soon as possible. For this to be possible I need a LOT more hours and a LOT more money (to fund CPL after GS). I would say if all you want to do is fly for a living, get good A Levels/Highers then get a job to earn some money for a few years. If your working in a crappy job with the aim of flying commercially, there's your motivation to be sensible with it, to save up,and to resist drinking it all away
A degree does look good on your CV but it does have an effect on your finances if you need money to fly commercially. Just my thoughts
