Pippins, I was a carer in my teenage years too. It's a tough task and you have my full admiration and respect. You obviously have the aptitude. I've been flying in the airlines for nearly a decade now. I've been with BA for the last two years. I have very average GCSEs and only A/S Levels (I left school at 17). If I can do it, then you most certainly can. Good luck!
