A visa interview is not a test of how clever you are. It is a check on one thing: are you a genuine student who intends to study, can afford it, and will follow the rules? Everything you are asked is a way of getting at that.
Once you understand what is being assessed, the questions stop feeling random.
The three things they are really checking
That you are a real student. Why this course, this university, this country? Vague answers (“it’s a good university”) read as a red flag. Specific ones — what the course covers, why it fits your background — read as genuine.
That you can pay. Expect questions about tuition, living costs, and who is funding you. Know your own numbers. If a family member or a loan is paying, be able to explain it clearly.
That you will do what you said. Your plans after the course, your ties, your intentions — the officer wants consistency between your application and your answers.
Preparation that works
Rehearse the content, not a script. If you memorise answers word for word, you will sound like it, and a follow-up question you did not prepare for will throw you. Instead, know your course, your finances, and your reasons well enough to talk about them naturally.
Practising with someone who will ask you the awkward follow-ups is worth more than reading a list of “common questions” online. That is a large part of what interview prep with a counsellor is for — the mock interview and the honest feedback afterwards.
On the day
Answer what is asked, briefly and honestly. Do not volunteer a speech. If you do not understand a question, ask for it to be repeated. Calm and clear beats fast and polished.
