Hello,
I don't live to far away from you, however, I'm not at that address often.
I know a lad not far from me who did his A-levels and then got a of money from modelling over the summer and went to "Cabair" and from what I recall it was tough work but fun in other ways, he is know going down the commercial route.
I just got my A-levels and went to University then applied for the RAF and basically, I'm now flying out of Oxfordshire.
One thing I advise you to do is create a back up plan, I feel your heart is set to hard on being a pilot and there's hundreds of factors that could prevent you from being one. So, be prepared to fall back and do something else if it happens, then your not back to square one.
Good luck
