Dear Victoria,

Hello from England!  You wanted to know about my school.

Well, I go to primary school. I like going to school. School us fun and all my class mates are very nice. My school is not very big but my class room is very big. There is a class zoo in there!

We've got a lot of subjects at school. I find school work easy. My favourite subjects are Art, Englisg,Maths and Music. I'm good at reading but I am not good at spelling. I hate spelling tests. And I don't like doing my home work. Best of all I like breaktime. 

Do you like going to school?

Is your school big?

What are your favourite subjects?

Is there a computerclass in your school?

Write soon,

Jessica
