Монолог про плохие оценки, плохое поведение (на английском)

Today school life is rather hard for teenagers. On one hand there is a lot of homework and on the other parents and teachers require you to do your best and get only good marks. That's why a lot of students get tired and start getting bad marks and there behavior leaves better to be desired. As for me I'm not good at geography simple because I don't have enough time for studying it. Some boys in my class are rude to teachers also because they are tired of endless studying.
