Напишите сочинение на английском: "На что часто жалуются ученики".

In my opinion, there are really three distinct things about which the majority of the students complain about. Firstly, a lot of the students indicate that their schools don\'t allow for much of the academic subjects, including the lack of ability to choose ones. Secondly, every single student complains about not having enough sleeping time, thus not being energized during the school. Finally, it\'s important to mention the fact that students don\'t like arrogant teachers who think too well of themselves and are not able to accept the constructive criticism.
