Part-1 (Speaking) consists of questions to check your ability for everyday conversation hence; it would not be advanced English. It is just to test your verbal skills in an academic environment.
This includes your Read Aloud, Repeat Sentence, Describe Image, Re-tell Lecture, Answer Short Question.
For example, in Read Aloud, a text of around 60 words will appear on your screen, you will be given approx. 35 seconds to go through the given text, as the timer begins you are supposed to respond, i.e., speak in a native manner, with clear-cut meaningful sentences. You can pause to represent punctuation to gain points; don’t forget to be active with a microphone as a pause for more than 3 seconds will disable your microphone.
