co-education and sigle-sex school(男女校and男校,女校)

No, I do not agree, since teenagers will fall in love easily, no matter where they study, they will have an equal chance to meet who they like whether they study in a co-education or a single school, those who study in single school can easily meet someone they like from outside.

If I have a choice I will study at a co-education school, since people do live together with the opposite sex in this world, then it should not have a single sex school, just for about eight hours a day, since at the end of the school day they can meet people of the opposite sex for the rest of the time.

Is that ok?

I think study in a sigle-sex school is better than a co-education school. Because I had an experiences of it, when I was primary student(co-education school), Iwas very naughty because there were many little things happened. after I studied in a sigle-sex school in secondary school, there was a great change on me perhaps I study much much better then when I was in primary school and my behavior are very well.
There must be some problems in a co-education school, so you must think twice are you want to study in a co-education school.
Hope my opinion would help you!
