Band 6+: What's the difference between swimming in the pool and swimming in the sea?

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

The answer is relevant to the question and makes a good start by pointing out the difference in water quality. However, it needs further development to fully explore the differences. Consider expanding on other aspects such as temperature, waves, marine life, visibility, and the overall swimming experience. More detailed comparisons would strengthen the response.

Good start, but the response lacks a strong conclusion. The slight hesitation and repetition ("it's the, it doesn't have...") slightly impacts fluency. Try to plan your answer briefly before speaking to improve coherence and reduce filler words.

Vocabulary is adequate and mostly accurate. Words like "disinfect" and "components" show good range. Consider using more precise language to describe the differences in water composition (e.g., salinity, temperature).

Grammar is mostly accurate, with a few minor slips. The sentence structure is generally sound. Improving sentence complexity and using more varied grammatical structures would enhance the score. For example, instead of simply stating differences, try to compare and contrast using comparative structures.
