Just that, really. I know selection is on variety of things, but academically DS is on exactly 90th centile (CAT tests). HM thinks he will sail through CE in due course.
Would far rather DS was happily swimming along in second quartile on everything in a good school than miserably scraping by in fourth quartile in a great school, so i am trying to get a feel for where this level would fall in terms of Eton.
