The state primary school I went to was 1 form per year and very pleasant, so the rich parents sent their kids to it, tutoured them for the 11+, and if they didn’t pass fee-paid them anyway.
The way the 11+ worked here is as follows:
Cream of the crop (5%?) offered a free place at single sex college which is mostly fee-paid to.
Next bracket (or any of the 5% who didn’t put the single sex college as a choice) offered a place at mixed-sex Grammar, which has no fee-paying
Everyone else, fee-pay to college or go to your catchment state school.
My dad got a pass to college. He was bullied by the rich fee-paid kids for being a poor kid who passed to get in. My younger sister got a pass to college, she got bullied by the rich fee-paid kids for being a non-rich kid who passed. 40 years apart and different schools, you’d think classism were still a thing.
My dad, despite being one of those rags-to-“riches” neglected estate kids with talent was pleased when the 11+ got done away with.
He said that as we all went through school, you could see the system being gamed with tutours more and more, while the estate kids got left further and further behind.
Hopefully as well, the state schools will be mopping up more MC kids whose parents may have been able to tutour but not commit to college fees, so that local politicians feel more pressure to keep the state secondaries in good nick.
