I've returned to this headline several times over the course of today. It appears to have now changed to "Girls fare better than boys under more rigorous courses" which at least implies some level of participation in their own success.
I've read for years theories that girls do better with coursework as they are "more diligent" than boys and I suspect these new "rigorous courses" were expected to "redress the balance" as it were.
I feel really cross about this headline and the implication that the format of an exam can be seen to benefit one sex over the other and that's the underlying reason for the disparity in results.
