Although it is the shortest section, it also has the most questions - you have to answer 36 questions in 25 minutes. So, you get an average of 40 seconds per question. Keep in mind this is not a golden rule- some questions might take you longer. We’d strongly advise, that for the more challenging questions, take a maximum of 40 seconds to come up with an answer; if you can’t, make an educated guess at an option, and flag it. If you have time in the end, you can come back and have another go.
