Mina hii im a current nossal yr 9 student i know the test changed from edutest to acer so i cant say too much about the content of the test now. when i did the sehs entry test in 2022, the math test had some surd questions. i dont think there were any trig questions, but when i did practice tests, there were a few. remember that the actual test wont allow a calculator, so there wont be any complex evaluation trig questions. regardless, id recommend u familiarise urself w most of the yr 9 math concepts and yr 10 if possible. vr was shockingly easy with the questions being simple to understand, however i know a lot of my friends struggled with it because they didnt understand the meaning of a lot of words. a good vocabulary is definitely the key to succeeding in vr. i built up my vocab over time by keeping a word bank, finding definitions and regularly revising them. rc was way easier than i expected as well. all the passages were max one page, so u wont get 7 pages worth of text for 3 questions. instead of working on stamina (which ofc is still important) focus on reading for meaning. there were some poems in there, so familiarise with understanding poetry as well. a lot of the answers in rc were very similar to each other, which made it a little hard, but tons of practice and process of elimination rlly helped out. if u want more info on what was in each of the tests, how to prep or anything else lmk!!
