Write to your pen friend about the school subjects you have.use the words from the box

Dear Saimon,
 My school began on the first september , that why  i was writing to you  quiet rarely, until  this  summer ended. Actually I'm already tired. Some of my school subjects are too dificult for me . Also my hometasks on this week are really large.
But In this letter I want to tell you about some of my favourite subjects.
I really like cheme, cause this lesson teachs me  , from what liquids and things are consisted . And i think that is as important as physic and geography.These subjects explain and describe people the world. Also  i find  anatomy really interesting. And that' s great , that people can know everything about their bodies. But unfortunatly i've got just 1 hour of anatomy  weekly.
And what about u? Please tell me about your favourite subjects in your next letter.
Miss u,
