Make proper use of the image to predict the topic of the lecture.
You have 3 seconds before you listen to the recording to quickly look at the image on the screen. Use this time to think about the vocabulary you might hear. This will give you an idea of the topic of the lecture and help you predict what you will hear when the recording begins.
Make good use of the 4 seconds speaking time. You only have 4 seconds to speak and make sure that you include all the main points of the lecture.
If you repeat ideas, do not correct yourself or hesitate, you will use up valuable time and lose score points. So keep talking and ignore any mistakes that you make.
