Dear Sir or Madame,
I am writing to you, because I am interested in holiday language course in Scotland. I would like to find out about language courses at your school, because I saw your offer in internet.
I am student from Poland. I go to the high school and this year I will write final exams. I learned English five years at school. I can write and read in English, but I would like to speak in this language, because it is my dream.
I will be in Scotland at holiday, because there live my grandparents. I think that I will spend there two weeks, because I would like to visit beautiful places.
I would be very grateful if you could send to me the information sheet of your language school, because I heard good opinion about your courses.
I look forward to your answer.
Yours faithfully,
XYZ
