I can see a lot going wrong with this. For example, boy classes/schools getting more advantages than girl ones.
Anyways, I must be from a different planet, because when I was in jr. and sr. hs I couldn't care any less what guys thought of me, matter of fact I was more concerned about how other girls thought of me. I think if I went to an all girls school or had classes with all girls that would have been torture for me.
I kind of think that's why sorority life (not the show) wasn't for me. Too much estrogen!
I guess for the guys and girls who ARE easily influenced by the opposite sex, it can be a good thing.
