Band 5+: Book sales distribution in a book store at a specific year.

The report appropriately addresses the task by describing the main trends and comparing the categories. It correctly identifies the highest and lowest sales categories and provides a clear overview. However, there are a few minor lapses: the final category's percentage is not specified, and some phrasing is slightly awkward (e.g., 'reaching for more than a third', 'a fifth sales'). To improve, ensure all data points are mentioned and refine language for clarity and precision. The report falls short of the required 150 words.

The report has a logical structure with an introduction, an overview, and body paragraphs, but the flow is disrupted by some awkward phrasing and a missing clear separation between the main trends and the details. The final 'overall' statement is placed after the detailed description, which is acceptable, but the transition between paragraphs could be smoother. To improve, ensure each paragraph has a clear central idea and use cohesive devices (e.g., 'In terms of', 'Regarding', 'Furthermore') to link sentences and ideas more effectively. Also, avoid abrupt shifts, such as moving from the second-highest category to the minor ones without a clear connector.

The vocabulary is generally appropriate for the task, with some good attempts at paraphrasing (e.g., 'illustrates the proportion', 'accounting for', 'the most readers' choice'). However, there are some inaccuracies and unnatural collocations, such as 'reaching for more than a third' (should be 'accounting for' or 'constituting'), 'a fifth sales' (should be 'a fifth of sales'), and 'the unspecific category' (should be 'the unspecified category'). To improve, use a wider range of precise vocabulary related to data description (e.g., 'comprise', 'constitute', 'account for', 'represent') and ensure collocations are natural. Also, avoid informal or vague terms like 'the most readers' choice' - instead, say 'the most popular among readers'.

The report contains several grammatical errors and punctuation issues that affect clarity. For example, 'children's books which read by younger people was accounted for a fifth sales' has subject-verb agreement and passive voice errors; it should be 'children's books, which are read by younger people, accounted for a fifth of sales.' Also, 'reaching for more than a third' is incorrect; it should be 'accounting for more than a third.' The sentence 'This indicated that fiction books were the most readers' choice' is awkward and should be 'This indicates that fiction books were the most popular choice among readers.' Additionally, the final 'overall' is not capitalized, and there are missing commas after introductory phrases. To improve, focus on subject-verb agreement, correct use of relative clauses, and ensure each sentence is grammatically complete. Practice using a variety of sentence structures, such as complex sentences with relative clauses and subordinate clauses, to demonstrate greater grammatical range.
