Yeah, the argument is that at least one subject needs to be compulsory
a UAI would be impossible to calculate without a common subject
But it seems unfair that english is the common subject, especially to people who are crap at english, and it is an unfair advantage to those good at english but not maths. In most education systems, maths and english are compulsory subjects, and the rest are whatever u choose, but in the HSC, only English is a compulsory subject
If english is to be the only compulsory subject, there should be options similar to general maths. there is really very little difference between standard and advanced, but a huge difference between general and 2u
while general teaches all the basics, and not the theoretical stuff like calculus, such a course does not exist in english. Even standard teaches some random analysis of texts, and is not essentially the basics one needs to know.
I understand the arguments for a common subject, but both maths and english need to be compulsory, as well as a english course equivalent to the general maths course, simply fundamentals
