I personally disagree with the topic creator. I think the VCE is biased towards the humanities subjects.
If a person is really good at English, they would be really good at other subjects that require essay writing. Hence as a result their raw study scores will be higher meaning it will be easier for them to get the top scores.
However for Maths/Science students, no matter how good they may be at those subjects, thing is they still have to complete an English subject, which a number of them (myself included) are not any good at it. So in the end, it will be harder for them to achieve the top scores no matter how much their other scores scale.
Now think about this, what if English didn't have to be included in the top four. Then maybe the Maths/Sciences will have the upper hand, but until then it's really the humanities students with the advantage
