I think G-spots advice is bang on, forking loads of dosh for an integrated course now is a waste of money particularly at such a young age.
Without sounding rude many of us at 19 are still growing up, i.e. our values change as we get older. Ask any boy who makes an Airfix model of an ME109 and he'll probably say a fighter pilot or an airline pilot. The risk is you could borrow all this dosh from your parents and find out you don't actually like flying, what then?
Do as G-spot says, get a job and broaden your horizons and do a PPL.
