Help with the letter

Dear Jim.
Y I'm write writing to you because I'm interested about your course. First of all, I like asking  to ask about the number of students that will be in each class. I think that it'll be less than the year before. In addition, I like informing me would like to know about the teacher's reputation. My mother tells me this all day. It's boring. (I don't understand this, why is it boring if your mom asks you this question?) One more question : What kindes of resources there are there? It's enquiring I'm inquiring due to England's weather. (It would be better to say, "What is England's weather like?") But it's possible that It'll be fun and incredible. Moreover, I don´t think to I'll have any expenses until the day will came. (This sentence sounds very unnatural, I would say, "I don't think I'll have any expenses until I come to England")  I'm fed up owing  to be living/being here.  Thank you.
Your faithful. Yours truly,
Manuel.
