Single-sex education or schools with boys and girls?
Both are options.
I prefer single-sex education, assisted by my experience.
Obviously boys and girls are different and have different ways and styles to study and learn.
Moreover the school subject of English can be the one with more varied levels of English. So if you have schools of boys and schools of girls you’ll have fewer levels of English and the class-groups will be more homogeneous. / Photo from: Group Of Students www marshall edu
