Hey, I don't think your race is too much of an issue. I get some snobbery towards me saying as Im not from your average middle class background, which most pilots are. You may get the odd funny look of people, but I don' t think it will affect your career prospects.
What I would say is consider your ability in the chosen subjecta, if you are good at maths and physics, then go for it, if not choose something esle; two grade Es in Maths and Physics may not be seen as good as a B/C in IT, English and so on ...
