How to answer this topic better
This topic works best when the example feels authentic and specific.
Introduce the friend, say how you met, describe one strong quality, and give one example.
You can record an answer, review the transcript, compare it with a stronger sample answer, and retry the same prompt without losing the main idea.
A friend I trust very much is someone I met in secondary school. We became close because we had similar interests and spent a lot of time studying together. The main reason I trust this person is that he is honest and calm, especially when I have a problem. I remember one time when I was confused about an important decision, and he listened to me carefully instead of giving a quick answer. That made me feel supported. He is important to me because I know I can talk to him openly without feeling judged.
This feels like Band 6 because it uses one clear quality and one example well, though it could sound more natural with richer detail.
