Should boys and girls be in separate classes ?
According to research , we can agree that boys and girls learn in different ways.Also normally girls tend to be smarter than boys, therefore that's another reason we shouldn't be separated. Scientist proved that having different ways to learn something you understand it better.
"Choosing the type of education your child should receive can be one of the most important decisions you make.
