Band 5+: The line graph gives information about the usage of Facebook and Twitter.

The report addresses the task by describing the main trends in the usage of Facebook and Twitter over the period. However, there are several inaccuracies in the data (e.g., Facebook usage in 2012 is stated as 21 instead of 35, and Twitter usage in 2015 is given as 13 instead of 24). The overall trend is captured, but the description of Twitter's performance is misleading, as it is not the most popular at the beginning, and the statement that it surpassed Facebook at the end is incorrect based on the data. To improve, ensure that key figures are reported accurately and that the overview correctly reflects the relative usage of the two platforms. Additionally, organize the information more clearly, perhaps by describing each platform's trend in separate paragraphs, and avoid vague phrases like 'it's number' and 'fwas used'. The report falls short of the required 150 words.

The report has a clear overall structure with an introduction and separate paragraphs for each platform, but the flow is disrupted by abrupt transitions and unclear referencing. For example, the phrase 'it's number' is ambiguous, and the shift from Facebook to Twitter lacks a clear linking phrase. To improve, use cohesive devices such as 'In contrast' or 'Meanwhile' to connect the two data sets, and ensure each paragraph has a clear topic sentence. Additionally, the conclusion is missing; a brief summary of the main trends would enhance coherence.

The vocabulary is adequate but limited, with some repetition (e.g., 'increase' used multiple times) and informal phrasing (e.g., 'it's number'). There is an attempt to use a range of expressions like 'experienced a significant decrease' and 'slight increase', but these are not always accurate or varied. To improve, use more precise and varied vocabulary, such as 'peaked at', 'dipped to', 'remained stable', and 'surpassed'. Also, avoid informal contractions and ensure terms like 'usage' are used correctly (e.g., 'the number of times' instead of 'number of usage'). Boost vocabulary complexity to elevate the overall score.

The report contains several grammatical errors and awkward phrasings that affect clarity. For example, 'At the beginning period' should be 'At the beginning of the period', 'it's number' should be 'its number', and '2015 a slight increase' is missing a preposition. There are also issues with subject-verb agreement and article usage. To improve, focus on sentence structure, use a wider range of grammatical structures (e.g., passive voice, complex sentences), and proofread for common errors. Punctuation and capitalization (e.g., 'twitter' should be 'Twitter') also need attention.
