ok first of all, without homework, children and teenagers can't get better education since imagine kids spend like 9 hours at school learning but they're actually not focusing, and just playing and chatting with friends so they don't actually lear anything. Then at home, imagine they don't have homework, that just means they didn't learn anything on that school day because they didn't focus at school and didn't receive any elements and materials to help them at least get like 40% if education at home. Also, when they have homework, it is preparation for college and future examinations. If they don't, then how are they going to study or remember the education information that they received at school?
