A letter from an English girl

Dear friends,
I'm writing this letter from England.My name is Nell Smith.I'm thirteen years old.I go to a secondary comprehensive school.It is a very large school.In our country there are many schools where boys and girls study together,but there are also some 'boys' schools and some 'girls' schools.
Our school is very large and we have very many teachers and pupils.We have a headmistress,a deputy head,more than thirty teachers and about a thousand pupils.As it is a comprehensive school there are many academic and non-academic subjects.You may choose even such subjects as nursing and housekeeping.
We go to school five days a week,from Monday to Fridai.On Saturday and Sunday we have a holiday.I get to school at 8.45 and start my lessons at 9 o'clock.We have five lessons in the morning:two before break (in which we drink our milk) and three after break.After our lunch we have two more lessons.School ends at 3.40 and I usually go home.
When I get home I start doing my homework.At school I learn thirteen subjects:English,Mathematics,French,German,Science,history,geography,needlework,art,games,physical training,music and religious instruction.
In conclusion I would like to ask you some questions.Do schools in Kazakhstan differ greatly from our comprehensive school? Do boys and girls study together or in separate schools? What subjects are taught at your school? How many subjects do you study? What is your school day like? Is it different from our school day? Please,write to me about your school.
