Band 6+: You recently tried an unusual or extreme sport for the first time, and something unexpected happened. Write a letter to your friend. In your letter: - Explain what sport it was and why you decided to try it. - Describe what unexpected thing happened during the activity. - Invite your friend to join you next time and suggest a date.

The letter effectively addresses all three bullet points: it explains the sport (bungee jumping) and the reason for trying it (despite fear of heights), describes the unexpected event (a loud crack and the strap moving), and invites the friend to join on a specific date. The tone is friendly and appropriate for a letter to a friend. Minor lapses include a slightly abrupt opening and a lack of detail about the experience, but these do not detract significantly from the task. To improve, you could add a more engaging opening, elaborate on the feelings during the jump, and make the invitation more enthusiastic. The letter falls short of the required 150 words.

The letter is well-organized and easy to follow. The paragraphs are logically structured: introduction, description of the event, and invitation. However, the transition between the description of the unexpected event and the invitation could be smoother. Consider using a linking phrase like 'Despite the scare, I really enjoyed it' to enhance cohesion.

The vocabulary is appropriate and clear, but there is room for more variety and sophistication. For example, instead of 'I was very scared,' you could say 'I was terrified' or 'I felt a surge of panic.' Also, 'a loud sound - crack!' could be more descriptive, such as 'a sharp cracking noise.' Using a wider range of adjectives and adverbs would elevate the lexical resource. Boost vocabulary complexity to elevate the overall score.

The grammar is accurate with no significant errors. The letter uses a mix of simple and compound sentences, which is good. To improve, you could incorporate more complex structures, such as conditional sentences (e.g., 'If you come, we can go together') or relative clauses (e.g., 'The jump, which was my first, was thrilling'). This would demonstrate greater grammatical range.
