Just had a phone call from her Head of Sixth form to ask if she is prepared to do this, on behalf of her school (a co-ed state comprehensive) to argue the other side!
It is true that personally, she has probably done much better in a mixed school as the desire to "beat the boys" was always strong
Also, as she "failed" to get a place at the single sex grammar school, and did not get amazing CAT results in Yr 7, she is very "value added" for them.
Do you agree girls are better in single sex schools (I think boys are!) or that they benefit from the extra competition in Male dominated subjects?
