this is coming from a person who forgot to check 2nd and third round offers for the exam and was a successful candidate
for the people who are doing the yr 8 sehs exam to get into yr 9, do NOT and i repeat, do NOT focus on much of surds since when i did them (this year), there were none, the math and nr were extremely challenging, as the writing exam prompts most likely revolves around one idea, for this year, it was about cinemas.
i recommend going through a yr 9 math textbook for all the math resources (aus curriculum), as i could not remember much of the math sorry
for the nr, it was extremely challenging, recommend focusing on patterns such as number patterns in boxes and decoding strings of numbers (which was surprisingly difficult), as the decoding strings of numbers may be a secondary focus for the exam due to the unlikeliness ACER will pump out similar questions, but i do recommend focusing on them still.
for the reading comp of the exam, there will be at least one poem for the exam, we had 2 this year, and the big texts are most likely going to be snippets of a book, so i recommend reading some books for the prep, from the range of 5-10 books before sleep, that's what i did.
verbal reasoning was piss easy, recommend going to tuition brances such as JAC (james an), as they replicate the reading and verbal pretty well, as for the math, it was kinda beyond what they provided in the tests, being harder. nr was sorta similar
they do give 'ai' generated prompts which is sorta frustrating, but if you do manage to achieve a superior (or above average) in every JAC test, most likely you will get in.
if you are attending JAC tuition, i recommend doing the book questions and the online simulation tests (not the humanities, that's obsolete) at connected class.
i also do recommend attending the big simulation tests from hendersons, and if you have enough shillings to pump out, go to hendersons
