Band 5+: Why did you choose this kind of work/to study this subject?

Your pronunciation is quite good. Working on consistency and tackling difficult sounds may enhance clarity.

The answer addresses the question but remains quite brief and somewhat vague. While you mention career goals and language improvement, the connection between your specific field of study/work and these benefits is not clearly explained. To improve, try to elaborate on the 'why.' For example, explain what your specific career goal is or how this particular subject specifically helps you interact with people. Aim to provide more context to make the response feel more complete and natural.

The answer is very brief and lacks development. In IELTS Speaking Part 1, while answers shouldn't be long essays, a single sentence or two is often insufficient to demonstrate fluency. You should aim to expand your answer by providing reasons, examples, or consequences. For example, instead of just saying it helps your career, explain *how* it helps your specific career path.

The vocabulary used is very basic ('need', 'helps', 'people', 'knowledge'). To reach a higher band, you should use more precise and sophisticated collocations. Instead of 'achieve my knowledge' (which is also a slight collocation error), you could use 'enhance my proficiency,' 'broaden my horizons,' or 'expand my linguistic competence.' The refined answer correctly identifies 'improve' as a better verb than 'achieve' in this context. Boost vocabulary complexity to elevate the overall score.

The grammar is technically correct in the refined version, but the range is extremely limited. You only used simple sentence structures. To improve, try using complex sentences with subordinating conjunctions (e.g., 'Since I aim to work in an international environment, I decided to study this subject because...') or relative clauses. This will demonstrate your ability to handle more sophisticated grammatical structures.
