I'd like my daughters to try the 11+ and Channing, St Margarets, Highgate and SHHS seem to be the only ones which appeal to me location wise. But how smart do you really need to be? I have one extremely driven to do well, a 2nd also smart but more reserved/shy, both very good at Maths and sport. Not massive readers. Im wondering whether to give it a shot without tutoring but not sure if the children already there are exceptional.
