Band 6+: What kinds of exercises are popular in your country?

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

The answer is quite good and directly addresses the question. Consider expanding on the popularity of biking by providing more details, such as the different types of biking (road biking, mountain biking), where people bike (parks, roads), or the social aspects of biking. Adding a brief mention of other popular exercises would further enhance the response.

The answer is coherent and easy to follow. There is a slight hesitation and unnatural phrasing in the first sentence. Improving fluency would involve smoother transitions between ideas and more natural sentence structures. For example, instead of 'I think biking is a way of exercise or popular in Vietnam,' consider 'Biking is a popular form of exercise in Vietnam.'

The vocabulary is adequate and mostly accurate. Words like 'affordable' and 'significant' are used appropriately. However, using more precise language would enhance the response. For example, instead of 'the effect that it has on our body is also high,' consider 'it offers significant health benefits.'

The grammar contains minor errors. The sentence 'I think biking is a way of exercise or popular in Vietnam' is grammatically incorrect. There are also some minor issues with articles and prepositions. Focusing on accurate article usage and preposition choices would improve the grammatical accuracy.
