It is said usually that girls in general are better students tan boys. It is true in many, many cases, yet not always – this is something evident.
Either man or woman has their own way of being. And their own different psyches.
I remember some cases when I was making a tutoring session with parents at the school about their son and it showed up that his sisters were more careful with their school material and that they studied more, as if they were more prone to studying than boys, who were more prone to play soccer on some town sport fields.
Another experience anyway: I have taught in boy schools and found kids that reached the CAE or the Proficiency, if I remember right. CAE is the Certificate in Advanced English examination from the University of Cambridge in the UK. Proficiency is the highest examination of the same university.
