I had an awful experience at state school. Bullying, ridiculed for wanting to learn, some really rough kids with violence, lots of smoking etc. The teaching was dire and some of the teachers preferred to chat then teach. Swathes of the syllabus simply wasn’t taught in maths and the education in general was massively dumbed down. I was incredibly bored but didn’t have the confidence to study alone as I thought I was stupid. There was no way I could ever bridge the gap to be able to get into such an exclusive university as Oxbridge albeit I have a degree.
Dd didn’t want to go to private secondary despite the offer being there. However, she and a few of her friends subsequently left state secondary and are far far happier. They were at different secondary schools and those at dd’s school in particular hated their ofsted outstanding state comprehensive school.
They all went to different private schools as we could pick the ones best suited to their needs. Incidentally none of them are ultra competitive. Dd’s school is probably requires the highest level academically to be admitted but is a far cry from the large, more competitive schools, which didn’t appeal to my dd.
One of dd’s friends, who was school refusing is now going every day, in a very small, nurturing environment.
This @SillySmart is why my dd has been in private school from yr9. Not to get her into Oxbridge. If your dc gets on at grammar, that’s fine. They’ll be massively advantaged anyway already being in a selective school.
