Watching students in class, I see most people waste the same opportunity.
Asked a question such as Where are you from?, they answer exactly that and stop. No development, no extra detail about themselves, nothing beyond the literal reply.
Why that is a waste
When you pay to learn English, what you are buying is an hour of talking to a teacher and to other people. That is an opportunity to speak with real humans.
Speaking is the one skill you cannot teach yourself. You cannot practise it with a mirror, and talking to an AI tool is still not the same as talking to a person.
So when someone asks you something, use it. Pull out everything you have: vocabulary, grammar, ideas.
The reframe
Take an ordinary classroom question like Where are you from? and treat it as the question an IELTS examiner asks the moment you walk into the room. How would you answer then?
Why wait? Plenty of people like to sit down and announce that today they are doing a mock test, which sounds impressive and serious. In that frame they answer at length and answer properly. Then in ordinary conversation they go right back to clipped replies: What's your name? My name is Thi. And stop.
Treat every question as practice. Use the most advanced vocabulary that still fits naturally. Extend the answer. Add an idea, add an example. Make it resemble a real speaking test.
If you are aiming at band 6, try to sound like band 6 even in casual classroom conversation.
