Write a note in which you ask someone to do a favor. j`ai cours demain s`il vous plait aider moi

Dear James,

I hope you are fine.  I would like you to do me a favour.

Tomorrow morning I have got a doctor's appointment and I will not be able to attend the morning courses. And I was wondering whether you could so kind as to give a copy of the courses.

Please let me know if you agree. 

Of course, I shall do the same for you in case of need.

Kind regards

Your friend John
