In Part One the examiner is allowed to repeat the question TWO TIMES if you don’t understand it. lf you don’t understand a certain word and ask about that word, the examiner is not allowed to explain it; the question will be repeated in exactly the same way. If you do not understand the question in Part One or if you just didn’t hear it clearly, it is fine to ask the examiner to repeat it. Use the following language
I'm sorry I didn’t quite catch the question; could you ask it again please?
I'm sorry I missed that one; could you repeat it please?
In Part Two, it is unlikely that you will need the examiner to repeat anything because the examiner doesn't actually say much. However, if there is a word on the topic card that you don't understand, then the examiner is allowed to quickly explain that word to you (usually by replacing it with an easier word or giving an example).
In Part Three the rules are less strict. The examiner will explain vocabulary, change the wording of questions or simplify the questions whenever necessary. This shouldn’t happen very often because when Part Three begins the examiner should have a very clear idea of your language level and he / she will ask the questions in a way in which you should be able to understand quite easily.
