The speaking part of the test lasts for between 11 and 14 minutes.

Part 1: The interviewer checks your identity and asks you a few questions on some easy everyday topics such as hobbies, family or food. This part of the test takes 4 - 5 minutes.
Part 2: You will be given a card with a topic on it. You have 1 minute to prepare to talk about this topic for a minute or two. This part of the test takes 3 - 4 minutes.
Part 3: The interviewer will have a discussion with you about some of the points you made in part 2. This part of the test takes 4 - 5 minutes.
