It is a culture among the harder working students to pick these standard subjects, so when scaling is calculated, we get higher scaling for these subjects.
I'll put it frank though, there is a culture among students wanting to do well, to pick subjects like chemistry/physics and so on and when they pick it, they do well in it and other subjects hence scaling it up. You don't have as many of these types of students (asians etc) picking humanities due to the general culture of it.
wrong.. I'm not trying to brag here, but for statistics sake I go to a 2012 top 5 ranked school, it's selective and a girls school. so hmm you might know where I am already but that's not the point. And also the majority of our school is asian, even in the humanities department the ratio is probably preserved
sorry for tl;dr response coming up btw
the number of people (at my school) doing modern history is around 50 something in my school, compared to chem at 100, bio at 20-30 and physics at 33. number of people doing Hist ext at ~50, legal at around 35, ancient at 23 and eco at around 50 or so too. now you can see that lots of people at my school are doing humanities more than the range of sciences available. apart from chem because I think everybody thinks chem is cool or something, not too sure but the latest prac threw everybody around in terms of time and detail of answers required. There are about 70-90 people doing 4U maths in our school (not too sure atm because lots are dropping) and for 3U + 2U inclusive there are 88 students.
I'm sure that people pick humanities in my year because they don't like science or they do badly at it, so it is more favourable for them to pick stuff like humanities as they know their effort will not go to waste, I asked a couple of my friends in ancient who don't do sciences at all why they didn't choose something like bio, which has a lot of content in it. they said that they just sucked at science in year 10 and hated it so they didn't bother choosing. and yet, with their mostly dominated humanities subject combo they are marginally (by a few marks = 10% already) beating me in ancient lol. to say "It is a culture among the harder working students to pick these standard subjects" is an insult, we state ranked more this year in modern history, ancient and economics and legal than ever before, to say that these people doing humanities are not as hard working as those doing sciences are 3/4 unit maths is truely sad. state ranking is hard in itself, let alone in humanities it is easy to miss mentioning herodotus in your essay and getting a mark off, putting you behind a couple of people that got 25/25 in your assessment already. to say that state ranking for science/maths is harder than humanities - hey if you didn't know your essays in humanities are double marked - that is one marker gives you a mark, and another marker does, and you get an average of their marks, which are non-nego. getting a 25/25 is harder due to this btw, making state ranks just as hard as any other subject and they are calculated to a decimal point.
If you haven't looked at the merit lists, look at IPT - the top 10 state rankers are 8 people from NSB and they are all in year 10 doing accelerated. that is a hard feat in itself, considering only 1 NSB state ranked for it last year also as a accelerant. This NSB cohort is just as hardworking as a ruse cohort at any subject, just because IPT isn't like maths or science doesn't mean the cohort is immediately less hardworking because they chose a theory subject, rather than a calculation based one. Getting a state rank in IPT or any humanities cannot be matched by a 90 in physics, chem, bio or 2U/3U maths. you can't define students as hardworking because they do chem or 4U maths, these subjects aren't known for their prestige or something. they're just hard. Is the JRAHS state ranker in chem, bio, physics and Maths ext 1 & 2 more hardworking than the SGHS state ranker in English Adv, Modern History, Ancient? No, getting a state rank is hard in itself, you cannot say that the histories are easier than studying for sciences/math, to get to be the top of the top needs major scrutiny and work both at home and in the exam and to also make sure that the effort you put in won't easily be iffy with a HSC marker especially for history which doesn't have set in stone criteria like maths/science. So they both require lots of work to master.
