If you can't play the system, then shut up and brute force it instead.
But you can't beat those who play the system and use brute force whilst doing so
Regarding languages, yes, the government offers a +5 at the mean both to encourage language studies and to reflect the difficulty of the content, but that's offered to all students. I agree that it's completely unfair that some native speakers get to do second language. VCAA try to address this with Chinese SL and Chinese SLA, as well as Indonesian SL, but it's still not quite a fair system. The fact remains that besides Latin, languages don't scale nearly as much as spesh, especially in the 40+ range.
Yes, that's right, the whole SL, SLA, FL divisions aren't fair, I know Chinese kids who have basically grown up in Australia speaking Chinese everyday, reading and writing well, technically they should be counted as SLA, based on ability, but since they were born here, they get SL and they end up getting like around 45 in Chinese SL, that really means that unless you're a native speaker, you won't get anywhere near 40, that's not exactly fair.
Secondly, true, most languages do not scale as much as spesh, but if you look at Chinese SL, Latin, Classical Greek, Hebrew, French, they all scale up massively. They are advantageous not because they scale up, but because they scale beyond 50. We all know that this year, it's impossible to get 99.95 unless you did a language and/or spesh (the aggregate required is greater than 210). Alright, so let's say there's a hypothetical scenario where I do two languages and spesh and get a score of 53 scaled in all of them (some go up to 55!) that's already 159, a decent score of 45 in English and that's 204, easily 99.95 with two 10% subjects.
See how you can get away with a 45 in English and still get 99.95, that's why languages are unfair, without them, you essentially have to get a 48+ in English to get 99.95, which is grossly unfair
