Band 7+: do you study best in the morning or the afternoon? why?

Your pronunciation is average. It is understandable but not always accurate. Focusing on the rhythm and stress patterns of English could prove beneficial.

This is a well-developed response that directly addresses the question. Consider adding a brief concluding sentence to summarize your preference.

The answer is coherent and mostly fluent. There's a slight stumble in the initial phrasing ('So to be honest, I'm studying bass at night. So what is the reason...'), which could be improved by streamlining it. The explanation is clear and logical, though.

Vocabulary is adequate and mostly precise. Words like 'disturbed' and 'efficiently' show good range. Consider using more sophisticated synonyms to enhance the lexical resource, for example, instead of 'disturbed,' you could use 'interrupted' or 'disrupted'.

Grammar is mostly accurate, but there are a few minor errors. The phrase 'every family member they feel asleep' is grammatically incorrect; it should be 'every family member is asleep.' The sentence 'I can have the power to do efficiently and faster' is also slightly awkward and could be improved for clarity and grammatical accuracy. Focusing on subject-verb agreement and sentence structure will improve this aspect.
