tbh i didnt even really study for it; the content they test isnt specifically in the year 9 and 10 sylllabus — im pretty sure it covers all the topics from year 8 and 9 science. the content is more holistic so its not those "straightforward" questions. the only practice i really did was the practice ones they had online but the test isnt hard, so you should be able to do pretty good if you somewhat listened in class
