Raw Marks are greater than Aligned marks.

Fuck these fucking assholes fuck them

atleast I have uac victim cards I can play to make up for this

Math Advanced scaling much better than English suggests that Math Advanced must be more difficult. Except it's not, you have to be retarded to get a band 4 or below since it's accounting for alignment. You only have to get a raw of 46/100 in the actual math advanced exam to get a 73 HSC exam mark. Meanwhile in English you need a raw 55/100 to get a HSC exam mark of 73/100, which scales incredibly low compared to even a 60 hsc mark in math advanced

Because people simply refrain from actually performing good in English. They dismiss it as unimportant or unnecessary, not considering that it has a significant impact on their ATAR. Standard especially is the worst because of so many dropkicks and ATAR Jokers in that subject. And some schools have advanced English as a compulsory course, which means dropkicks are present there as well. Maths on the other hand is not compulsory, so a lot of smarter people tend to get into advanced. Schools like Penrith, Sydney Tech and other selective schools also have advanced as a compulsory course, adding to that smartness. So, please take English seriously lmao.

 

[coolcat6778]

how do they even know how much to scale each subject to?

I think it's cause English both Advanced and Standard is full of dropkicks who can't even do basic algebra in other subjects so UAC thinks you have to be very good in English to not be the average and get a low atar contribution

yet another reason why English shouldn't be compulsory

English Advanced and Standard scale the exact same. The UAC calculator is lying to you because of limited data below 80 hsc mark. UAC themselves state they scale the exact same on their annual report. https://atarestimator.streamlit.app/ This is the most accurate atar calculator

Explanation:
The UAC compass calculator is extrapolating the graph of English Advanced for HSC marks below 78 from origin (shown as the straight red line) because for some reason UAC couldn't use the whole dataset for their public calculator. However, using the knowledge that all English scale the same as stated by UAC themselves, we know how Advanced actually scales (same as studies and standard) (the extrapolated graphs of each subject look slightly different due to limited datasets, however in actuality they should be identical).

Because it is extrapolating the graph, it over estimates scaled marks (and hence atar) below 78 hsc mark since the curve is significantly concave up below 78. (math advanced knowledge)

This calculator https://atarestimator.streamlit.app/ from https://www.linkedin.com/posts/grah...p&rcm=ACoAAEdlYqYBx3Iby66yKAAsHsYneQxUl__wWpM correctly accounts for this and is probably the most accurate atar calculator. Otherwise, when calculating atar using UAC calculator, put english standard regardless if you do advanced since that gives the most accurate scaling data for marks between 67 and 96

The truth is that scaling has nothing to do with how difficult a subject is. In fact, the UAC says this explicitly every single year in their scaling reports (which people seem to conveniently ignore):

The scaling process is carried out afresh each year. It does not assume that one course is intrinsically more difficult than another or that the quality of the course candidature is always the same.

The myth that scaling is based on difficulty is a classic correlation vs causation misinterpretation. Think about it, difficulty is individually subjective. Some people find Chemistry more difficult than Physics whilst others may find it easier. There is actually no way to objectively quantify difficulty.

So then what is scaling based on? For 2 unit courses, it is based on how a cohort performs in their other subjects on average. In other words, it is purely driven by the data. As an example, suppose we have two cohorts in say Chemistry and Physics. The reason that Physics generally has a higher scaled mean is because the Physics cohort is typically stronger in their other subjects. However, as a thought experiment if you hypothetically swap the cohorts between Chemistry and Physics, then does Physics still get a higher scaled mean? No, it will be Chemistry that gets the higher scaled mean because now it contains the stronger cohort. Another way to think of it is that the underlying scaling shouldn't change if all we've done is swap the subject name between the the two cohorts. Obviously the reality is more nuanced than that due to external factors, subject content etc, but that is the underlying principle behind scaling.

Bottom line is that it is all data driven. The relativities are not set in advance.

So for your implied question on why does Maths Adv get a higher scaled mean than English, it is because the Maths Adv cohort performed better than the English cohort (which is most of NSW) on average in their other subjects. The opposite can also happen. It is possible for Maths Adv to get a lower scaled mean than English, if its cohort ends up doing worse in their other subjects. It's just unlikely to happen in reality due to external factors such as the selection bias of students who choose to do it versus compulsory English.

that ATAR calculator made me realise just how much English cooks me

also correct me if I'm wrong, but I thought you couldn't extrapolate a direct relationship between the returned HSC mark and the mark NESA uses for scaling? because NESA uses raw marks to calculate both separately which means that there is no direct relationship? I'm not sure

it's accurate enough. The data actually comes from the UAC report themselves, where they tabulate some HSC marks against some scaled marks

Also Y axis doesn't mean atar equivalent, it means scaled mark out of 100. But the UAC report reports it out of 50 and HSC marks out of 50.
An 80/100 scaled mark is good for a 95 atar provided u actually get that scaled mark in all subjects

 

[coolcat6778]

these people are directly responsible for making a subject scale lower than usual. fuck them

do you know how autistic you have to be to get 9 out of 100 marks and still pay $40 to view ur mark? i genuinely hope this guy is in hospital right now

 

[coolcat6778]

Retarded dogshit English is most likely used as common ground for scaling by UAC. Math should be used as common ground instead since English doesn't correlate with intelligence.

NESA and UAC need to get rid of shitty mandatory English. Western Australia only requires you to complete English, however it doesn't have to count towards ATAR.

Who the fuck goes "this person knows how to write like shakespeare, he must be soooo intelligent" like shut the fuck up.

According to UAC, Math Extension 2 could scale badly if everyone in the state did it since scaling is based on performance in other subjects. Math Extension 2 should always scale the same based only on mark distribution in the exam

Given your many threads obsessing over scaling, they are now all streamlined into one thread and put in the right forum. Please post any future rants in this thread rather than keep making new ones. Thanks
