Swimming and cycled KK? There be dragons down that path.
We all the did the 11+ at school, twas mandatory.
I know! I'm a runner, let's not bastardise that with these other strange elements (yet again) 
The school system down here is still old fashioned and we live in a very affluent area; bucking the trend by being very unaffluent ourselves. Basically the bright kids go to the grammar schools, the moneyed but thick go to the private schools and the rest go to the comps.
Ok the moneyed and bright also go to the private schools, or the grammar schools.
Although, intelligence in my book is multi-factored, so some of the best kids go to the comps.
I like comprehensive schools generally, having chosen never to work in private or grammar schools for a reason.
Not that I'm opinionated at all.
