Might aswell jump onboard...
I'm 22, have a BSc in Biology from the University of Durham and am now half way through the CTC Wings Cadet scheme.
I'd definitely recommend getting a degree 1st, you never know when your medical may let you down or the industry take a downturn. I was told by many a pilot to have the degree as a back up, so I did.
University also teaches you so much more than you could ever learn in a lecture... something which I feel can only better you as a pilot.
