Thanks @eco-alex . Yes, my oldest has developed remarkable understanding and abilities with computers and the internet, which is something he probably wouldn't have learned in school. In many ways , the school system is outdated and ill equipped to prepare children for the reality of the fast changing world they are growing up into.
Saying that, I think me and you learned quite a lot in school - particularly in practicing ways to beat the system - and also made some lifelong friendships, so it's not all bad.
