Semi-Formal

Tips for success

6 key tips

1

Read the prompt carefully. Understand which type of letter is required and exactly what points you must cover.

2

Match your tone to the situation. Formal letters need formal language; informal letters can use contractions and a friendly tone.

3

Organise your letter clearly. Use a proper opening, structured body paragraphs, and a suitable closing.

4

Address all bullet points. Every point in the prompt must be covered — missing one will lower your Task Achievement score significantly.

5

Practise different letter types. Familiarise yourself with formal, semi-formal, and informal styles so you're ready for any scenario.

6

Proofread. Leave a minute or two at the end to check for grammar, spelling, and punctuation errors.
