Band 5+: Your family is planning a big celebration (like a birthday or anniversary) and you want your cousin to join. Write a letter to your cousin. You should include details about: what the celebration is and when it will take place; why it's important for them to be there; offer to help with their travel or accommodation.

The letter addresses the main task of inviting your cousin to a family celebration, but there are several issues that detract from its effectiveness. The celebration is described as your father's birthday and 'fifth anniversary,' which is confusing. The date is given as 'Monday 13th' without specifying the month, and the letter is written in the past tense ('yesterday had been birthday'), making it unclear if the event has already occurred. The importance of the cousin's presence is not clearly explained; the reasons given (memories of the aunt's cooking and a promise about allergy-free meals) are tangential and not directly tied to why the cousin's attendance matters. The offer to help with travel is present ('I can pay you a ticket'), but it is vague and lacks details about accommodation. To improve, clarify the event (e.g., 'my father's 60th birthday'), specify the date and time, explain why the cousin's presence is meaningful (e.g., family unity, the father's wish), and provide concrete offers for both travel and accommodation (e.g., 'I can book your flight and you can stay with us'). Also, ensure the letter is written in the future tense if the event is upcoming.

The letter has a logical structure with an introduction, body, and closing, but the flow is disrupted by unclear references and abrupt topic shifts. For example, the transition from discussing the celebration to the memory of the aunt's cooking is not smooth, and the connection between the father's promise and the cousin's attendance is not clearly explained. To improve, use clear topic sentences for each paragraph and ensure each paragraph has a single main idea. Additionally, use cohesive devices (e.g., 'Firstly', 'Moreover', 'In addition') to link ideas more effectively.

The vocabulary is basic and sometimes imprecise, with errors such as 'fifth anniversary' (likely meaning 'fiftieth birthday' or 'fifth birthday'), 'cellebration' (spelling), and 'do not order you any meals' (awkward phrasing). There is some attempt at descriptive language (e.g., 'cheeseburgers with fries'), but overall the range is limited. To improve, use more varied and precise vocabulary, and avoid repetition. For example, instead of 'hard working job', say 'years of hard work'. Also, proofread for spelling errors. Boost vocabulary complexity to elevate the overall score.

There are numerous grammatical errors that affect clarity, including incorrect verb tenses ('yesterday had been birthday' should be 'yesterday was my father's birthday'), subject-verb agreement ('she used to cook us a cheeseburgers' should be 'she used to cook us cheeseburgers'), and missing articles ('It was his fifth anniversary' should be 'It was his fiftieth birthday'). Additionally, there are issues with word order and sentence structure (e.g., 'It is been the best days' should be 'It has been the best days'). To improve, focus on using correct past tenses, articles, and subject-verb agreement. Practice writing simple, clear sentences and then gradually incorporate more complex structures.
