In your situation I would probably go to university. You said that you are sitting your exams now....have you passed AFCO? I passed a few weeks ago and I doubt if I will be in OASC for September. Some people wait almost a year before they have their final interview. You have to remember that unless they are activly recruiting in a feild it can be a slow process. Phone your local AFCO and see about the scholarship but I think it has expired for this year. The course that you have chosen to do would be good as it shows you are interested in flying as a career. But if you were offered the chance to fly commercially would you take it over the RAF? You should apply to different airlines to sponser you, they will usually pay all the costs as long as you join their airline.
