Most people in the state are allowed to exhibit weakness in a subject. For instance, if you are not doing so well in Chemistry, you are allowed to have that omitted from your top 4 calculation. My logic is the same. If people display weakness in English, how come they do not get the same consideration?
Firstly, I agree 100% with Gloamglozer; but your argument, phrased this way, intrigued me - so I guess I'll have to eat my words and reply! Briefly, briefly.
The only logical reason I can think of is that VCAA (and by extension, uni administration) don't allow students to "display weakness in English" because they believe, for whatever reason, that English is somehow a general predictor of success in tertiary education, and as such, that should be universally applied in such a way so as to _significantly affect_ a student's chances for admission to _any_ course (ie top 4 requirement).
I'm not saying that English is indeed such a general predictor of success in uni. Anecdotal evidence from my circle of friends doesn't really suggest to me that this is true. But just from the perspective of educational philosophy, I find it interesting to consider why VCAA might have thought this way.
General disclaimer: not the brightest bulb in the box - I may have missed something in my reasoning, etc etc.
VCE is another planet all together; you've made it through and you're on planet Earth now. Things are a lot more logical and make more sense [emphasis added]
LOL, I was so sleep-deprived and caffeine-addled throughout VCE - poor time management - that the planet analogy hit very, very close to home!
I agree with ILMM though that those are very much "words of wisdom" that spring from a well-rounded view of the role, and the privilege, of education. VN itself is kind of a rarefied environment in terms of academic success, and yet I think we have retained a healthy perspective, despite some individual disappointments.
