I think its hard to get really high marks like in the 90s but high 80s is doable/easier to achieve.
even a low 90 is doable. my raw mark i calculated ended up in the range from 87-90 depending on how many marks they give me for stuff. but a lot of the marks i lost were carried errors and easily avoidable. 94 is the boundary where beyond that you have to be prodigious

I would say a lot of students in the top selective schools would get raw marks in the high 80s, even low 90s. Hence, why you see the 99s and 100s which make up most of the state ranks. It definitely is possible for students who may not go to the top schools to get these high raw marks, but not as prevalent.

my estimate is 75 for e4. rui from atar notes said "This, however, has got to be the most draining MX2 paper I've done in a very long time. The only other time I recall of feeling so defeated was in 2018 or something where the chaotic Euclidean geometry question showed up" according to the raw marks database, in 2018, an e4 cutoff was exactly 72 raw but tbh i think more people did better in this exam than i originally thought so e4 might be higher like 75-77, possibly 80. a raw of 90 might then scale to a 95. would be amazing if it was closer to 2014 scaling, raw 90 scaled to a juicy 97.
What does he reckon raw 55 goes to lol, i think the lowest in my class reckons she got 55/100, hopefully it goes to like 80 🙏🏼

anything above 50 will probably be above 70, so probably like 74 or something

ah yes the classic article where boomers question why we still do things like this because it has no value to society. a pattern ive noticed is that top schools always get the opp to do this.

interesting they picked 16b, what about a and c? I wonder if just not many had a sufficient answer for c
maybe because b had the most marks.

plus i hate how they say this is the hardest q in the entire hsc. this is not it by a mile and a half because you cant brand anything as the hardest q. how do you compare this to an essay q where there are multiple right answers

yeah thats true, but out of all 3 surely b is the most like a normal question
ikr it was pretty tame for being the hardest q. the only way someone can screw up is effing up the vomit algebra at the beginning.

they did hold your hand until the algebra, just the amount of variables i magically made a u^2 become u^3 and i wouldnt be suprised if others did the same somewhere

it was t for me. for some reason a t vanished from one of the terms so my quadratic ended up having 2 terms as the constant, therefore the discriminant was fugly and basically barred me from justifying as well. i reckon recognising discriminant with a carried error will warrant at least 3 marks hopefully but maybe thats too lenient, ive seen other say that getting the quad is enough for 3 but i dont think so

somehow my mistake turned out into great theta values so i assumed i had done it right...
