I wouldnt send my children to a same sex school.
While i have heard of the two sexes doing better in their studies if seperated , I have also heard of some having sex releated issues. I dont mean gay or whatever but some do find it hard to iinteract with the other sex, while others go hell for leather to make up for lost time.
Also , not exactly same topic , but not far , I wont be sending my child to a Public school either. I have experienced both public and private and a local catholic school is my preffered choice. This may ruffle a few feathers but the public schools i have been to are nothing short of ****ed!
