Band 4+: You recently attended a training course that was much shorter than advertised. You feel that the course did not cover all the necessary information. Write a letter to the training course provider. - Explain what course you attended and when. - Describe what aspects of the course were missing or incomplete. - Apologize for any inconvenience, but request a partial refund or further training.

The letter addresses all three bullet points required by the task. However, the development of these points is quite thin. While you mentioned the course details, the specific unsatisfactory aspects, and the request for a refund, the descriptions are very brief and lack the depth expected in a professional complaint. To improve, try to expand on your points with more specific examples (e.g., instead of saying 'materials were old,' explain that they referenced outdated software or methodologies). Additionally, the tone is somewhat blunt; using more formal, sophisticated language would better suit a professional business letter (e.g., instead of 'The course was not good,' use 'I found the quality of the training to be below the expected standard'). The letter falls short of the required 150 words.

The letter follows a logical progression, addressing the three bullet points required by the task. However, the transitions between sentences are very abrupt, making the writing feel 'choppy.' To improve, use cohesive devices and linking words (e.g., 'Furthermore,' 'In addition to this,' or 'Consequently') to connect your ideas more smoothly. The paragraphing is functional but very basic.

The vocabulary used is very basic and repetitive (e.g., using 'not good' or 'not useful'). For a professional complaint letter, you should aim for more sophisticated and precise language. Instead of 'The course was not good,' consider 'The quality of the training was substandard.' Instead of 'I want some of my money back,' use 'I am requesting a partial refund.' Expanding your range of professional vocabulary will significantly improve your score. Boost vocabulary complexity to elevate the overall score.

The sentence structures are mostly simple and repetitive (Subject + Verb + Object). There are several errors that affect the professional tone, such as 'the course I attached' (which should be 'attended') and 'talk to each much' (which should be 'each other'). Additionally, there is an incorrect comma in 'I look forward, to hearing from you.' Aim to use a mix of complex and compound sentences to demonstrate better control over English grammar.
