HI
I have to agree with scroggs there in that you should try and get better marks if you want to go do the sponsorship route. Have you had any flying experience??? Cause if not I would suggest that you have a couple of trial flight to see if you really do like it and then decide whether to go to night college. Believe me its extremely hard to get sponsored and they will want some kind of proof that your able to work hard before they spend thousands on training you.
If your looking at the self sponsored route - may I suggest South Africa for PPl and hour building - a lot cheaper and the weather is great - most of the time.
Good Luck
