My ante natal group have been having this debate as a couple of them paid for private schools and tutored with the view to getting into the local grammer but their children didn't pass and they are now going to the local state high school.
Whereas a couple of kids who did go to the local state primary are now going to the grammer.
I'm just interested in MN views, although I'm obv aware of the tension and conflict over private v state
so go easy!
