Literature is different to English, it's more competitive.
How is that meant to make a difference? Competition affects scaled scores. I'm talking about a 23 raw score. For example, one would expect that a student who scored all A's for food tech would get the same raw study score as a student who scored all A's for specialist maths.
Oh and when I say these grades, these are the scaled grades. Obviously not everyone who gets C's in SAC's is going to end up with a C on their GA (general assessment) when they receive their VCE results. I'm talking about the grades that are actually printed on the VCE results sheet, NOT the grades that your teacher gives you during class.
Having said all of that, I can see your point because VCAA is retarded and although a C+ is supposed to be the median grade for every subject (ie. all C+'s will get you a 30 raw score), that is not always the case. For some unknown and illogical reason, VCAA decided to be inconsistent with their grading system, thus making the whole grading system pointless, since it doesn't actually tell you anything.
They might as well make the median grade an A+ for one subject, so that all A's will get you a 25 study score, then make the median grade a UG for another subject, so that all D's will get you a 40 study score. That's how stupid the system is.
