It's not scaled based on difficulty, but rather the strength of the cohort. Higher achieving students tend to do common subjects, and lower achieving students tend to stay away from those subjects. Because there is the perception that lower scaling subjects are easier, the result is that lower achieving students would fill those subjects, hence reducing the mean of the total marks. If say all lower achieving students did Physics, then Physics would likely become a low scaling subject since the strength of the cohort compared to others is weaker.Although UAC may scale them depending on its difficulty in order to determine your ATAR, the marks we received today are our official HSC marks
