*scaling is like disadvantaging some students for not being able to do harder subjects.
Pretty much this, and there is absolutely nothing wrong with it either. Though it is the pessimistic approach. You can say it like that, or the optimistic one is "scaling is an advantage for some students who do harder subjects". The above statement however demonstrates the other end of the spectrum. Because I dont find it fair if 70 Raw in 4U should be equivalent to 70 Raw in General Math. Other people wont find it fair if their hard earnt 90 in Chemistry or Economics is just as equivalent as someone getting the 90 Raw in a VET subject or Food tech or something.
But of course, these are just the extremities in the scaling system, what happens within it however, where you have distinguished from subjects like Legal to Physics or Biology from Business etc.
I like to think of it as the way scaling is determined, is that the more logic and thinking a subject involves, the more scaling it has. For example, rote learning is virtually non-existent in 4U math, Economics and Chemistry as well to an extent. For English, there is just general diffifcult aura around it. You need to be able to write a deep blistering essay in 40 min, and although some people memorise essays, (which I am against), you cant simply memorise all throughout English, there is a point where you have to use your natural ability in the exam. And as you go down the scaling spectrum, the easier it is to memorise your way through thoughtlessly.
Thats the way I see it I guess...
