Dear Sir or Madam,

I am Giang, 17 years old. I live in a Northern province of Viet Nam. As you see, I have just 17 years old but I have a poor memory. This situation started 4 years ago. I cannot remember the works i must do and usually stuck in troubles. It is also harmful for me to study many subjects such as: history, geography, biology,... and so on. I really worried about it but cannot find the method to improve my memory. Luckily, I saw your advertisment for a course designed to help improve memory. I extremely curious about the method of the course and also want to attend it. I also have many question for you : ''How much is it?'' and '' What the date your course started? ''.

Thank you for reading my letter. I hope you will respond my letter.

Your faithfully,

Giang.
