Hii,
If you're still taking answers there's one thing to know about these selective tests: they may vary in testing conditions and the quantity of questions every year. I hope you're handling the pressure well because it'll influence your resulting performance.
I only distinctively remember the test session for writing (sorry):
Writing: You were given a 40m time limit to write both a persuasive and a creative essay. This meant that you had to manage your time frame well and have at least one essay finished. The topics of the tests were quite similar to each other (i.e. they were both about astronomy). For creative writing they gave an image prompt this year.
I honestly recommend going to a tuition or online course to collect resources regarding the selective exams. It was also very helpful for me to print out practice tests or complete them online.
Here's a website I used: https://www.oztests.com.au/courses/free-vic-selective-and-scholarship-practice-tests/
I hope I helped you somewhat and wishing you the best on your selective exam preparation! π₯²
