Band 6+: The graph shows Internet usage at one of the Russian universities from August to November 2021. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The report addresses the main trends and provides an overview of the data. However, there is a significant discrepancy between the data provided in the visual description and the figures reported in the text. While the examiner is lenient regarding AI-generated descriptions, the report's internal consistency is weakened by using specific percentages (e.g., 17%, 60%, 65%) that do not align with the provided data points. To improve, ensure that the reported figures more closely reflect the trends and values presented in the visual, and aim for a more precise comparison between the three groups throughout the entire period. The report falls short of the required 150 words.

The report is well-organized and easy to follow. The use of cohesive devices such as 'Overall', 'Regarding', 'On the other hand', and 'Meanwhile' helps guide the reader through the different categories effectively. To reach a higher band, you could attempt more sophisticated transitions between sentences to create an even more seamless flow of information.

The vocabulary used is appropriate and accurate for describing trends (e.g., 'increased significantly', 'stayed almost the same'). However, the range is somewhat limited. To improve, try incorporating more varied synonyms for 'percentage' (such as 'proportion', 'share', or 'figure') and more diverse verbs to describe changes (such as 'fluctuated', 'peaked', or 'declined').

The report demonstrates a good command of grammar with high accuracy. The sentence structures are clear and error-free. To achieve a higher score, try to incorporate more complex sentence structures, such as combining observations using relative clauses or participial phrases (e.g., 'Students saw a significant rise in usage, peaking at 75% in October before dropping slightly in November').
