Application letter

Dear Sir or Madam
I saw your adverstiment on the our busy music shop on the High Street and am writing to apply for the job of Saturday as a shop assistant.
I am fifteen years old and am a Year 4 student at Mediterrania secondary school.
According to my teachers, I amb hard-working. My friends say that I am outgoing, confident and a polite person, so I belive I am an ideal person to work as a shop assistant there.
Last summer, I worked in a shop for two months. At present I haven't got a job because I am preparing for my exams.
I enclose my CV and a recent photograph, and I look forward to hearing from you soon.
Yours faithfully.
Laia Moreno
