Livre d'Or

I was in single-sex education from age 8 to 16 (and I was quite isolated from boys, as I didn't have any brothers, and didn't get involved with church until the summer of GCSEs).

Unlike you, I do think it hindered me pursuing science/tech subjects: because it was an all-girls' school they just didn't think they needed to offer those subjects as much as a mixed school might have. They only offered double-award GCSE science rather than three separate science GCSEs, and they didn't offer computing/IT GCSE (they did make us do the CLAIT course, which as far as I can tell is for people who want to be secretaries). They offered GCSEs in Food and Textiles instead.

Luckily, only having double-award science didn't actually stop me getting to do maths and science A-levels at a mixed sixth form. Once there, I was the only girl in top set Physics and in most of my Further Maths classes, so I expect if that had been an all-girls' school those classes wouldn't have existed.
