Religion and Life Issues (PC alert!) was made compulsory in my school which was not a religious school of any kind. Athough my school was a "Language College" which of course emphasised on multicultralism. I now study Relgious Studies at college (I am one of two students from my school who study it - at least at my college

). I am interested in religious points of view and the moral side of it though I decare myself of no faith.
There are of course many benefits of having same sex schools, I know the Girls' school in my city has attracted a large number of Muslim students - this may help them feel less worried about male attention and teenage boys looking at the students "provocatively". And of course an all boys' school prevents this and at time of prayer there would not be no worry about the male/female divide which is a core rule of worship.
But our Boys' school in our city often has the lowest GCSE grades for the city and that could be down to the steriotypical view of boys being rough and 'ard. So it can effect the students potential.
