Hi Francie
Welcome to the bug that is Aviaiton, for what it's worth, I left school at 16, had ok GCSEs, went to college, learnt my trade doing a fantastic job that I loved for a long time before turning to aviation. I was "old" when I got into the system, I took the modular route, I had an ok upbringing.
Basically nothing was going for me in any respects, especially if you put the job on a pedestal and stereotype the kind of person you "think" would fit the bill, I most certainly wasn't this person.
All I can say is that if I can do it then anyone can, (provided you can fly & pass exams of course) believe me on that one. If you want any more info feel free to PM me.
