Your logic is interesting.
Because nearly anyone can pass the HSC as well.
In HSC, they rarely give out aligned marks below 50. (if that's what you assume it to be "pass")
Only few one digit per cent of the entire cohort gets something below 50 aligned marks.
Very interesting.
Your mark in VA would have been fairly high (assuming that you got Band E4 for Mathematics Extension 2 because you are doing a Distinction Course).
Are you the one who state-ranked in Visual Arts (9th from what I see) from Kambala?
How much do you spend on each maths (in terms of percentage/hour of your whole study time/maths study time):
4 unit maths
3 unit maths
2 unit maths
Example:
1. 4 unit maths = 1 hour = 20 % of my whole study time = 50% of my maths study time
2. 3 unit maths = 1 hour = 20 % of...
It's important to note that "bonus" UAI is not actually added on to your UAI.
As suggested above, it just increases the applicant's ability to get into the desired course.
Yes, it has been generally accepted by many evidences gathered from this website & from my own experience that aligned marks are higher than raw HSC exam marks.
