Band 5+: You have recently booked a venue for a family celebration, but you need to change some of the arrangements. Write a letter to the venue manager. You should include details about: - the original booking details - the specific changes you need to make - how these changes will affect the final cost

The letter addresses all three bullet points required by the task. The original booking details are clear, the changes (increased guest count, buffet style, and venue change) are specified, and the impact on cost is mentioned. However, the response is slightly weakened by some logical inconsistencies and grammatical slips. For example, the writer states that a buffet will 'increase' per-head charges, whereas in many contexts, a buffet is a cost-saving measure compared to a three-course sit-down meal; while this is a matter of opinion, the reasoning could be more clearly articulated. Additionally, there are several typographical and grammatical errors (e.g., 'tha', 'servive', 'rather then', 'Iam percieving') that, while they do not impede communication, prevent the response from reaching the higher bands. To improve, ensure that all transitions between ideas are smooth and that the relationship between the changes and the cost is logically sound. Proofreading for spelling and punctuation will also help elevate the overall quality.

The letter follows the required structure and addresses all three bullet points, which helps the reader follow the purpose of the letter. However, the flow is disrupted by several punctuation errors and awkward sentence structures. For example, starting a sentence with 'And' or using 'However' incorrectly after a comma breaks the logical progression. To improve, focus on using cohesive devices (like 'Furthermore' or 'Consequently') more naturally and ensure that each sentence connects smoothly to the next without abrupt stops or fragments.

You have attempted to use some topic-specific vocabulary such as 'alterations', 'reservation', and 'revised invoice'. However, there are several spelling errors (e.g., 'servive', 'percieving', 'prefered') and incorrect word choices (e.g., 'individuals' instead of 'guests', 'perceiving' instead of 'realizing' or 'noticing'). To reach a higher band, work on your spelling accuracy and focus on using collocations that sound more natural in a formal business context, such as 'guest count' instead of 'number of individuals'.

Grammatical errors are frequent and occasionally impede the clarity of your message. There are issues with article usage (e.g., 'in the event' instead of 'for the event'), preposition errors, and sentence fragments (e.g., 'Due to sudden shift in our planning, However...'). There are also issues with verb tense and structure (e.g., 'and thinking of' should be 'and we are thinking of'). I recommend practicing complex sentence structures and paying close attention to subject-verb agreement and the correct use of punctuation to separate independent clauses.
