St Helier,
1) Have you looked into applying to organisations such as GAPAN, RAFA and Air League? All have scholarships and bursaries available to young people like you. The Air Cadets is a very good suggestion, they offer flying and gliding scholarships to their members as well as a BTEC in aviation studies.
2) A quick google will reveal that some flying and gliding clubs in the UK offer scholarships to young people. Contact thse clubs, pay them a visit and find out what might be on offer.
3) Join your local flying club. If you can't afford to pay for flying training then join as a social member, the people you will meet will have much to offer. Most pilots enjoy flying keen young people and often a quick hand with re-fuelling or help washing the aircraft is payment enough.
4) Send a CV to the flying clubs in your area offering assistance or part time work. Again there could be spare seats available and the experience will be good (not to mention the extra money you could earn).
5) As J.A.F.O mentioned earlier, gliding can be a very enjoyable and inexpensive way of getting into the air. Junior memberships and discounted flying rates for young people are available at most gliding clubs.
6) Don't waste money having to re-sit exams, study thoroughly and practice exam papers as much as you can before sitting the real one.
Stick with it and have as much fun as you can on the way.
