Hi,
I was 14 when i started flying and it was amazing i flew solo on my 16th birthday and got my licence just after my 17th birthday as the weather stoped me flying for a while. I have just finished school now passing my A levels i would say that you want to make sure that complete your ground exams before you start your GCSE's as this along side your flying exams would be alot of work. As for not flying during your A level years of school isn't really a problem (well it wasn't for me) as long as you keep your school work priority it won't be a problem.
Good luck with your flying it will be a fantastic experience !!!
