Speaking form experience (ex-RAF), if the military want you to have a minimum level of qualification (or anything else for that matter) that's what they want. No ifs, buts or maybes - there's no flexibility - you have what they want or you don't have what they want.
As for flying experience, as has already been said, you could be a 747 training captain.... They're not interested, you do
their tests - you pass or fail, you complete
theircourse - you pass or fail. It's remarkably simple really, no confusion, no grey areas.
Stay at school, finish your education to the highest level you can achieve - this will present the most option to you in your future. You're still young (don't take that a being patronising) you have a great deal of time to make lots of decisions, I'm 36 and just started my CPL training........ there's always plenty of time

Good luck.
