Dear Mr Brown,
I am writing to ask for some further information about an english course in your school in England. I really would like to attend this course. It is very important to me.
Would you mind telling me how much will it cost ? I also wonder if there is any accommodation , where I can stay in ? Are there any extra course hours ? If it is possible, I can attend this course every weekend in July. My level is upper intermediate, but I want to learn more. I am very interest at English language.
I am looking forward to hearing from you. Thank you in advance.
Your sincerely,
XYZ
