What would you do if you didn't understand the phrase "status symbols" (see yesterday's questions)? Would you guess, or would you ask the examiner?
The good news is that it's fine to ask the examiner for a bit of help in part 3 of the speaking test (but not in parts 1 or 2). So here's what you could say:
"Sorry, I'm not sure what you mean by status symbols."
The examiner will then try to ask the question in a different way, and the fact that you didn't understand these two words won't affect your score.
