Oh yea, you might be too old to get it funded. But that doesn't mean you can't do it if you can pay for it yourself. Maths and Physics are very relevant subjects. You probably do want to get at least three though. I mean the BA FPP requires minimum three A-Levels at BBC. And the good thing about doing it that was is that if you don't make it with an airline then the A-Levels will still enable you to go to uni if you wanted.
That'd be my advice.
