Write to your pen friend about the school subjects you have.Use

Dear David,
I have received your message, where you asked me about my school subjects, so I would like to reply you.
Actually, we have many interesting subjects, such as History, Geography, which can give so exciting information for us. We also learn English - one of the most important and useful sudject, because we can not imagine our life without this language.
There are also dull and awful subjects, that I hate. It is Physics, Math, Chemistry. This subjects just make me bored.
So, you have seen my attitude to my school subjects. I hope, you will write such letter for me too.

Best regards.
