I'm not from the uk but live here, and my kids are in primary school. I think I have been grossly underestimating just how many children get private tuition. In a discussion with a group of friends, ds (y5) was actually a bit embarrassed that he was the only child out of 7 who doesn't have private tuition - he said 'my dad is my tutor, he's a. maths teacher so he is technically my tutor'. I was a bit surprised, is it really that common? He goes to a normal state school and is doing well at school, nothing exceptional but I'd say just above average in most subject.
