I've just been chatting to ds and his friend. The friend goes to a grammar, ds to a high school (aka secondary modern).
Ds says that the top sets in his school are almost all girls- friend says that at the grammar the classes are roughly 50:50.
Which got me thinking. Both schools are roughly 50:50 so does that mean that the "bright children do well wherever they go" applies to girls more than boys? Or what else might it mean?
