We’re free to experiment because we’re single sex and way less self-conscious – and the benefits don’t stop there. It never occurs to our girls that science is for boys, that being a leader is unfeminine or that it’s inappropriate to come top in exams.

No-one’s worrying about how they look, which may explain why our sports teams are so successful, why our drama students are so willing to experiment – and why the girls who stream out of our fabulous Visual Arts Centre don’t notice that they’re covered in paint or clay.

We’re more concerned with how they think, so the emphasis throughout the school – in the classroom and out of it – is on analysing problems, questions and opportunities and coming up with original and creative answers.

It’s a lot more effective than absorbing received opinion when it comes to exams, as our results show. In 2011, 94 per cent of GCSEs were graded A* or A and 44 per cent of the girls racked up at least nine A*s.
