I wonder why today's table for top 100 secondaries - state and private merged is not on line. Anyway it's interesting in general. 18 state schools in the top 100 and my older children's old schools at I think placed 2, 12 and 18. I think 5 year averages are fairer. No state school in the top 20.
Interesting article says that although some state schools do get good A level results although they're completely eclipsed by the private schools who only educate 7% of children, they aren't as good at getting into university and that perhaps the reason is the schools don't educate broadly and roundly beyond cramming for exams.
