It's all about pounds, shillings and pence really!!!
I'd put yourself in a position to have maybe 2 A'Levels - if you really want to go flying, then i'd start earning - why not start working around airports?
It's gonna be tough for the next few years so maybe get your PPL, have some fun but earn some money too, don't give anything to Oxford until you see and advert in the back pages of Flight International Magazine from British Airways! About 2011/12...you've got all the time in the world...
