My daughter (27th July) will be starting senior school in September aged just 11yr 1 month. She went for her induction day at the pretty selective school she will be attending, during which one of the activities involved the girls sorting themselves out into age order.
My daughter was the youngest of the 34, by nearly 6 weeks (the next youngest was June 15th, with one other earlier in June). The point is that there are hardly any girls born in the summer term. Anecodotal evidence that summer borns tend not to do as well academically even by the end of primary school, or mere statistical blip?
