I want to know more about writing memo

I want to know more about writing memo,and official letters,I’m working as a teacher,I think I’m poor in English writing.So please help me.

Hi,

Those areas are really too wide ranging for use to deal with as a forum question. I suggest you google using the keywords ‘memo template’ and ‘letter template’, then when you have a letter to write, post it in the forums and someone ewill help you review it.
