I know it's 'cool' to always rail against the 'establishment' and home in on its flaws, but I think VCE is about as fair as it could realistically hope to be. Let me refer to some examples of VCE's 'unfairness' here:
1. People capable of doing English or Literature are doing ESL.
This isn't really a fault of VCE, but rather civilisation's technical inability to derive someone's competency in language. We can't test students on this competency either as they'd just intentionally fail that test to enter into ESL.
2. VCE isn't fair because it punishes people who do poorly on SACs.
How is it unfair that students who don't work get a lower mark than those who do? SACs can be drastically scaled up if you really improve anyway.
3. The impact of English is too great on one's ATAR.
I partially agree. I don't know about you, but I want the surgeon operating on my nuts to be a fluent English speaker. I do admit however doing well in English is about far more than just speaking the language itself fluently, and that Science/Maths-minded students unduly must put in much more effort into this subject than Humanities-minded students.
4. SACs depend on favouritism of teachers
That's a fault of human nature, not the wider VCE system.
In summary, VCE isn't perfect, but to one-mindedly rail against it because you don't like it is an immature response to that fact. We shouldn't forget that our complaints, it seems to me, are mostly petty and centre on maybe one or two subjects and nuances in the scaling system. In the grand scheme of things, it leaves VCE a rather effective system albeit an imperfect one.
Don't get me wrong - I suffer from its flaws too. I do History: Revolutions in which the average exam score is something like 45%. The subject scales up by one.
