There is a lot of information for 6th Form Scholarships and further opportunities. You can even ring AFCO now to get the information.
You should apply now for consideration next spring and a potential for an award in Sep 08 when you enter the Upper Sixth. The award is paid to your parents.
Then depending on whether you go to university or become a direct entrant you will receive different levels of award. In other words you are not committed at the 6th Form stage.
There is no flying scholarship as such but there are other opportunities to fly. Speak to the AFCO.
