Band 7+: How could public transport in your country be improved?

Your pronunciation is very good. Aim to refine subtleties and intonation to further improve.

This response is relevant to the question and provides a suggestion for improvement. However, it could benefit from more detailed explanation and examples to support the suggested improvements. Elaborating on the advantages of a metro system or fast trains compared to the existing bus system would strengthen the response.

The answer is coherent and well-structured. The ideas flow logically. Minor improvements could be made by slightly improving the pacing and reducing the slight hesitation ('Even though it is good, I believe that there are other types that could be better than it').

The vocabulary is adequate and appropriate for the task. More sophisticated vocabulary could be used to enhance the response. For example, instead of 'better than it,' consider 'more efficient' or 'more effective.'

The grammar is largely accurate with only minor issues. The sentence 'Even though it is good, I believe that there are other types that could be better than it' could be slightly improved for conciseness and flow. Overall, the grammatical range is good.
