Hello! A few tips:
1.I had my listening task earlier, and what I did was write maybe like 5 topic sentences regarding discovery in different aspects e.g. self discovery, and then memorise them for the short essay so you have great topic sentences to make a strong point.
2. In the exam, make sure to back EVERYTHING up with either a quote you hear, a audio technique, AND links to discovery. You'll have short answer questions in which you'll have to relate everything to the AOS(Discovery).
3. When watching the clip, make sure to relate to the clip and create links. Create links, make sure it's a story you can visual, relate to. This, my friend, will allow you to remember quotes, techniques and hence, write better responses. We had a sorta clip where we had this advertisement type of thing where these young people discovered their capabilities and rediscovered their appreciation when challenging themselves in a isolated place. But really, I was about to create links because, if you're lucky, your teacher would also let you see the visual part too. This increased my ability to remember what they were saying, hence aced those marks
4. If you're still stressing, I recommend trying to practice AOS papers, the comprehension part. Try Last year ones, because, really, it's all about linking texts with a main concept. Try looking at sample answers, to see how Band 6 students structure their answers. That'll help.
Good luck!!
