The overall HSC mark that you receive in a subject (in this case, Economics), consists of two marks, the average of which produces the HSC mark. The first mark is the Assessment Mark, which reflects your internal performance in the subject. This is the mark that is determined according to your rank relative to your cohort as well as the performance of your cohort in the HSC exam.Speaking of which, I really don't understand how does the cohort thing work...
so for example if I ranked 14/55 in my economics cohort, does that mean I will get the mark from whoever ranked 14th in my school in the economics hsc exam.
If so what's the point we still study hard to do the exams?(especially for those ranked really low, even if they had a academic comeback in hsc, it's still gonna be somebody else's mark)
The second mark is the Examination Mark, which is the mark that you receive for your HSC exam. This mark depends solely on your own performance in the HSC exam of the subject, and is not affected by factors such as your rank relative to your cohort or your school rank.
