Band 4+: The charts show the percentage of electronics purchased in Cambodia in 2020 and the projections for 2040. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The report effectively addresses the task by summarizing the main features and making relevant comparisons between the two years. It clearly identifies the overall trends (increase in smartphones and tablets, decrease in speakers and computers, and stability in smartwatches). The data is mostly accurate, with minor omissions (e.g., not specifying the exact percentages for all categories in 2040) and a slight inaccuracy in describing the decline as 'in the past several years' rather than 'projected'. The report is well-structured and coherent, with a clear overview and appropriate use of data. To improve, ensure all key data points are included and avoid any ambiguous phrasing. The report falls short of the required 150 words.

The report has a clear overall structure with an introduction and an overview paragraph. However, the final paragraph is incomplete, which disrupts the flow and leaves the report unfinished. Ensure that all paragraphs are fully developed and that the report ends with a complete summary of the remaining data. Additionally, use a range of cohesive devices to link ideas within and between paragraphs more smoothly.

The vocabulary used is appropriate for the task, with some good collocations such as 'held the largest electronics purchases' and 'projected to remain entirely unchanged.' However, there is limited range and some repetition (e.g., 'at 10%' used twice). To improve, incorporate more varied and precise vocabulary, such as 'accounted for,' 'constituted,' 'anticipated to rise,' and 'expected to decline.' Also, avoid informal or slightly awkward phrases like 'stayed constant at a total of 10% of sales' - consider 'remained steady at 10%.'

The grammar is largely accurate, with correct use of tenses and structures. However, the report is incomplete, which prevents a full assessment of grammatical range. The sentence 'In contrast,' is left unfinished, which is a significant error in terms of sentence structure. To achieve a higher score, ensure all sentences are complete and demonstrate a wider variety of complex structures, such as subordinate clauses and passive constructions, while maintaining accuracy throughout.
