Я последний год учусь в школе и усе

Я последний год учусь в школе и усердно работаю, чтобы сдать успешно выпускные экзамены. Так как я очень занята, я не могу много помогать родителям по дому.
Однако у меня все-таки есть определенные домашние обязанности. Каждый день я убираю мою комнату и постель, мою посуду, протираю мебель от пыли.

I am a student at the school last year and hard work to pass the exams successfully. As I am very busy, I can't much help to parents in the home.
But I still have some household responsibilities. Every day I'm cleaning my room and bed, my dishes, rub my furniture from dust.
