The average cohort SAC result is what you get
No, not really, if you look the example above, your final SAC mark is the exam score of the student who achieved the exam rank equivalent to your SAC rank
the exam is the same all around Vic therefore it shows true smartness
True, that is why SACs are standardised to the exams
So if you get straight 90s in SACs and 50 in exams, the SACs were obviously easy compaired to other schools.
Again, your SAC score does not matter, it is the SAC rank. 90 could be the lowest score in your cohort, which in that case, you could say the SACS were 'easy', on the other hand, 90 could be the highest score in your cohort, which implies that you individually found the SACs easier, but overall cohort performance will also depend on the distribution of other students' SAC scores.
