chxin i sat it for year 9 entry as practice but the format should be the same.
writing:
i believe we had 30 (could be 25 i forgot) minutes to write about one narrative piece. the stimuli was a picture of a forest i believe. then again i could be wrong asf. but here's what to know - you only write one piece, not two like the sehs. i believe you get more time and there's no allocated planning time if i remember correcly. however, they would definitely be looking for quality of writing (i.e really good - as in literary level) and logic as opposed to quantity.
maths/nr:
ima just lump these together cos they go hand in hand. going into the exam, i'd heard tons of people say how hard the maths and nr was but i actually found these pretty managable. there was nothing harder than methods unit 2 (where they introduce differential/integral calc and probability), mostly just polynomials, functions, and ur typical questions u would have encountered in ur sehs prep. i recommend doing amc for these.
reading comp:
i found that reading comp was BY FAR the hardest. to put this into perspective, i found the SEHS one piss easy and, as far as i'm aware due to discussions from last year, i didn't get more than 1 or 2 wrong. one of the texts was an advertisement/article about bulletproof glass. questions included authorial intent, implications and connotations, and literary devices. also tone i believe - study up on the more niche ones that your school wont teach you.
verbal:
i dont even remember sitting verbal to be honest so i cant really help you. idek if there was a verbal component but if there was i think it wouldve gone hand in hand with ur sehs; only diff being that they assess more knowledge rather than logic ingenuity.
edit: i believe that scotch caters the level of difficulty of each component based on what theyre lacking in the current cohort. for instance, i know for a fact that scotch's scholarship students in my grade are crazy good at math (prizes in amc, awards in aimo, etc) but i think that they were lacking in the english department, hence why they made the reading comprehension so difficult. so take my experience with a grain of salt because their 2029 cohort could very much be english orientated.
