Dear Victoria,
Hello from England! You wanted to know about my school. 
Well, I go to primary school. I like going to school. School is fun and all my classmates are very nice. My school is not very big but my classroom is very big. There is a zoo's class there!
We've got a lot of subjects at school. I find schoolwork 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 homework. Most of all I like breaktime. 
Do you like going to school?
Is your school big?
What are your favourite subjects?
Is there a computer class in your school?
Write soon, Jessica
