The short answer
Identify the purpose and reader, cover every bullet point in its own paragraph, and keep the tone consistent from greeting to sign-off.
Choose the right tone
The prompt tells you who the reader is. A manager or company needs a formal letter; a friend needs an informal one; a neighbour you know a little often needs semi-formal language.
- Formal: Dear Sir or Madam, ... Yours faithfully
- Semi-formal: Dear Mr Lee, ... Yours sincerely
- Informal: Hi Anna, ... Best wishes
Cover all three bullet points
Missing a bullet point limits your Task Achievement. Give each one a short paragraph with a specific detail.
Opening example (formal)
I am writing to complain about the washing machine I purchased from your store on 3 March.
Manage your time
Spend about 20 minutes on the letter and save 40 for Task 2, which carries more weight.
