Hi Adam, from your posts it would seem that the financial side of all this "experience flying" that you are doing is not a problem. If so, then that is an excellent situation to be in.
As others have suggested, if by now you have had about half a dozen flights, then your instructor should really be taking you further along the learning curve, especially as your ambition is a PPL and then on to a CPL. The problem remains that at your current age, you are not going to be able to take advantage of the skills that the syllabus will give you. By all means enjoy the fact that you are in the air, but for me, In your situation, I would wait a while longer, I am sure that SFC are not going to discourage you spending money with them, but from some of the questions that you have been asking on this forum, the knowlege that should be coming from your flights, is not being imparted to you.
Best wishes and good luck to you anyway.
Meldrew.
