Band 6+: The bar chart shows the number of students enrolled at 3 universities in 2010, 2015 and 2020. 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 trends and providing specific data for each university across the three years. The overview is clear, and the comparisons are well-made. There are minor inaccuracies in the data (e.g., University C in 2010 is reported as 13k instead of 35k, and University B in 2020 is reported as 30k instead of 35k), but these do not detract significantly from the overall response. The report is well-organized and coherent. To improve, ensure all data points are accurately reported and consider using more varied sentence structures. The report falls short of the required 150 words.

The report is generally well-organized with a clear introduction, overall trend, and body paragraphs for each year. However, there are some issues with coherence and cohesion. For example, the use of 'While' to start a sentence in the overview is not ideal; it would be better to use 'while' as a conjunction within a sentence or use 'However' or 'On the other hand'. Additionally, the phrase 'after which it fell during last year' is awkward and could be rephrased as 'after which it fell in the final year'. The use of 'similarly' to start a sentence is also not standard; it should be followed by a comma and integrated into the sentence. These minor issues slightly affect the flow, but the overall progression is clear. To improve, focus on using cohesive devices more naturally and ensuring that sentence structures are varied and correct.

The vocabulary used is adequate for the task, with some good attempts at variation, such as 'admitted', 'enrolment', 'upward trend', 'considerable increase', and 'declined'. However, there are some inaccuracies and awkward phrasings: 'increased in students enrolment' should be 'increased in student enrolment' or 'saw an increase in student enrolment'; 'showed the highest enrolment of students which is almost 36K' could be more concise; 'the population of students' is not the best choice, 'number of students' is more appropriate; 'declined of by 10k' is incorrect, should be 'declined by 10k'. There is also repetition of 'students enrolment' and 'number of students'. To improve, aim for more precise and natural word choices, and avoid repetition by using synonyms or rephrasing.

The report contains a mix of simple and complex sentence structures, but there are frequent grammatical errors that affect accuracy. For instance, 'university A and C increased in students enrolment' should be 'universities A and C saw an increase in student enrolment'; 'While university B experienced upward trend initially' should be 'While university B experienced an upward trend initially'; 'after which it fell during last year' should be 'after which it fell in the last year'; 'which is almost 36K' should be 'which was almost 36K' for tense consistency; 'similarly the population' should be 'similarly, the number'; 'declined of by 10k' is incorrect. Punctuation is also inconsistent, with missing commas after introductory phrases and before 'which' in non-defining relative clauses. To improve, focus on subject-verb agreement, correct use of articles, prepositions, and tense consistency. Proofreading for punctuation would also help.
