Band 4+: You were supposed to attend an important event organized by a colleague, but due to unforeseen circumstances, you couldn't make it. Write a letter to your colleague, apologizing for your absence. You should include details about: - what the event was - what prevented you from attending - how you plan to show your support despite missing the event

The letter addresses all three bullet points: explains the emergency (mother's operation), expresses regret, and offers to make it up. However, there are some lapses in tone and clarity. The opening could be more polite, and the language is somewhat informal. To improve, use a more structured apology, ensure proper punctuation and capitalization, and avoid run-on sentences. For example: 'Thank you for inviting me to your birthday party. I was really looking forward to it, but unfortunately I had to cancel at the last minute because my mother needed an emergency operation and I had to look after her. I feel terrible about missing the celebration. To make it up to you, I would like to take you out for dinner or a fun activity when you are free.' The letter falls short of the required 150 words.

The letter has a logical structure but lacks clear paragraphing and transitions. Consider separating the apology, reason, feelings, and plan into distinct paragraphs. Use linking words like 'however', 'unfortunately', and 'to make up for it' to improve flow.

Vocabulary is basic and repetitive (e.g., 'sorry', 'fun'). Try using more varied and precise words, such as 'sincerely apologize', 'disappointed', 'cherish', 'compensate', or 'celebrate'. Avoid informal phrases like 'take you out somewhere'.

There are several grammatical errors: missing commas, run-on sentences, incorrect capitalization ('FRom'), and subject-verb agreement issues. For example: 'But i cannot attend your party i apologize' should be 'However, I cannot attend your party, and I apologize.' Work on sentence structure and punctuation.
