Thanks Binsleepen, very useful info I appreciate it. I am not worried about the minimum criteria BA stated because I think I meet them (9,1 in the international baccalaureate in Science and Maths, equivalent to an A/A*, I am not sure yet), plus I have a degree, speak 5 languages, have work experience in the aviation world and hold a PPL licence...
What I am worried about is the fact that I am not British, and therefore I am not a native English speaker...
It will be hard, but even if I don't meet the BA requirements at the end, I hope they give the opportunity not only to those guys who meet the criteria (there will be hundreds even thousands of them), but also to those who have shown an interest for flying.
Thank you again, and best wishes to everyone.
