My sons have just been for a tutor assessment - six hours of tests each, and the tutor suggested they would suit Kings' Wimbledon or Colet Court with a view to moving to St Pauls at 13.
We hadn't really considered either school, and had been looking more locally in Surrey (RGS, Hampton.)
If anyone has sons at either school I'd love to hear from you, good or bad. All I can find is very old MN threads saying CC is a hothouse. Is it? Or is it just for bright boys who like to do well at lots of things.
TBH, St Paul's looks ideal for one DT, who loves to do six impossible things before breakfast, but not the other, who likes to chill, which they actively discourage on the first page of their website!
