Очень с английским! Буду бесконечно благодарна

I'd like to describe you my working day. All the days looked very much the same.

On weekdays I usually get up at 7. I do my morning exercises. Then I wash my face and hands and clean my teeth. At half past seven I am ready to have my breakfast. I like to have a quick light breakfast. After breakfast I leave for school.

My school is not far from my house. It takes me 10 minutes to get to school. My lessons begin at 8.30 a.m. and finish at about 3 p.m. Six or seven lessons a day is the ordinary timetable. Twice a week I stay at school after classes to play basketball.

When I come home I have dinner. Then I rest a little. Sometimes I read a book or talk to my friends over telephone.

After that I start doing my home assignments. Twice a week I go to have private lessons in Maths in order to improve my knowledge.

As a rule, I finish doing my homework at about 11 o'clock. But one day a week is not so busy. This is Thursday. On Thursday I usually help my mother. Sometimes I do shopping or pick up clothes at the cleaner's.

I usually have supper at 8 o'clock p.m. Then I go on with my work. At 11 o'clock I go to bed.
