Band 6+: how many hours do you usually sleep at night?

Your pronunciation is above average. However, you may find complexity in certain words challenging. Regular practice should aid in improvement.

The answer is relevant and coherent. Consider expanding on the reasons behind the reduced sleep and the consequences of this change. Adding a concluding sentence summarizing your feelings about sleep would improve the response.

The answer is coherent and mostly fluent. There are a few hesitations ('uh'), but they don't significantly impede understanding. The structure is clear and easy to follow. Reducing the filler words would improve fluency.

The vocabulary is adequate and appropriate for the topic. Words like 'school student' and 'university student' are simple but effective. More sophisticated vocabulary could be used to enhance the response, for example, instead of 'more work to do' perhaps 'a heavier workload' or 'increased academic demands'.

There are some minor grammatical errors. The phrase 'it'imposs po' is clearly a slip of the tongue and should be corrected to 'it's impossible'. The sentence structure is mostly correct, but more complex sentence structures could be used to demonstrate a wider range of grammatical accuracy. For example, instead of two separate sentences, 'I would like to sleep more, but I think it's impossible' could be combined into one more sophisticated sentence.
