A am writing with reference to your advertisment in the "English" magazine. I have some questions regarding the course in English you offer.
Would you be kind enough to tell me how much a course like that costs and where the classes take place? I have been learning English for four years and I am on intermediate level.
I want to learn the language abroad, so that I could practise it on a daily basis, and communicate with native speakers. As I've never had any opportunity to learn English in any foreign country, I've chosen England to go to for the first time.
