What happens if I can't keep talking for 2 minutes in Part 2?
If you stop talking before the 2 minutes are up, the examiner will sit and wait for you to continue. If don't start talking again, the examiner will make a hand gesture for you to continue. If you still don't say anything, the examiner will say, "Can you tell me anything more?"
Not talking for the entire 2 minutes will affect your Fluency & Coherence score.
Many students worry that this will happen to them. However, you can avoid this kind of situation by following Chris' Part 2 strategy in Module 4 of the Speaking Academy course.
