Test takers will usually hear an audio (30s-90s) before required to choose a correct summary of the audio from given 3 to 5 options. This question type usually consists of 1 or 2 tasks.
Tips
Highlight Correct Summary questions account for an insignificant amount of points in the Listening Section, so they deserve a very low priority in preparation for PTE.
The key to this question type is to understand the audio as a whole, so never get distracted, like reading the question. And the given options differ in main meaning, not trivial details.
Time Span
Highlight Correct Summary questions account for an insignificant amount of points in the Listening Section, so finish them as quick as possible, leaving more time to more worthy WFD. If sure to answer correctly, can spend 1.5 minutes at most in each question( with audio playing combined in). If not, do not spend too much time here, just make a rough choice immediately after the audio playing and enter next task.
Practice Task
Before taking mock test or real test, practice 1 whole set of questions to get familiar with them. And pay attention to time management.
