Hello Mr.Smith
I am writing because I want to tell you about my English course in Cambridge.
I have to say that it was a really good course and I liked it very much, especially the way you conveyed knowledge. But there is one thing I would improve - the coursebooks - they are good, but I think for students on a more advanced level it may be a little bit boring. Would you like to consider changing them?
And I have a request. Could you send me the photos we've taken recently? The photos from our last classes. I will be grateful!
Best regards,
XYZ
