Thats cool advice, I am all too aware that this is a different animal as he totally switched off or his a levels. Being led down the garden path to stay at school to do a levels rather than college or an apprenticeship just so the school gets the funding is one of the things that will kill vocational trades such as mine. In my environment i am able to fast track certain students if i feel they are capable. He is highly intelligent and driven since starting the apprenticeship but now realises that the casting company he works for is leading to a very limited skillset. Heck the 2d cad technicians workstation would not even run inventor. He knows he needs more of a challenge. He is also working through most of the maths problems at college for the tutor who has not delivered that type of maths for two decades. As soon as anywhere gets funding to keep students it becomes a book keeping excercise. I would not want to be his age now.
Sorry for thre rant but the education system winds me up. I have seen too many promising individuals lost because their route to success required a different approach to the norm.
