Super school

At my super-school there are three classes.
Classes start at half past 9h. an they finish at half past 12h.
I go to school on Monday, on Wednesdey and Friday.
Today we’ve got Maths an Art. The obligatory subjects are Maths, Catalan, Spanish and English.
We have a school obligatory uniform, the blue trousers are and the withe shirt.
My favourite subject is Maths, because there are funny problems.
I have got a interesting Maths teacher.
I like my super-school because I invented it as I like.
