Welcome olivermitch99, welcome to Flyertalk and yes, you're in the right place, welcome to the BA forum. There are quite a few pilots contributing here, and a rather longer list who lurk. But thank you for the interesting question.

I can't shed much light on your position, by way of an answer, other than that you have gone for almost identical subjects that I went for, albeit they were O levels rather than GCSEs in my day. Add a Latin O level, and swap Spanish for French, otherwise identical, and it has served me well enough. My instinct is to focus on the exams immediately ahead, take it one step at a time. With good GCSEs you can build the platform. Oh and Duke of Edinburgh - which wasn't offered in my school - would have been the thing I would have done if I had my time again, it's one thing that separates a lot of very similar CVs. Not the DofE per se, but the experiences that came from it, it's a very worthwhile thing to do.

I guess the other point I can make is that I always read the pilot profiles in Highlife, BA's monthly inflight magazine. Your early aspirations would appear to be a very common feature in their experiences.
