your explanation is kind of wrong. person A should get 94 for both his internal and external - the reason for that is because the highest / lowest ranked person in the internal will get the highest / lowest mark in external - hence 94. and person F will get 60 for both as well. your explanation will be totally wrong if you think about what happen if the school assessment tasks were extremely easy. how could bos set a same standard across the state ?
other than that, the explainsyion on the the gaps of the marks are correct . : )
No, he's actually correct.
But I've also found that the smaller the gaps between individuals' internal marks the better it reflects on your cohorts' assessment marks. For instance, in English Standard, the gap was no more than 2 marks between 1st (me) and 3rd (other guy) after my school decided to remove a massive 5 mark gap between 1st and 2nd, unintentionally of course.
I ended up with 92 (exam) 92 (assessment) whilst 2nd ended up with 76 90. I've also noticed a discrepancy of up to 10 marks (assessment being higher than exam) across all my cohort, even in the lower half of the cohort. So it helps if someone in your cohort smashes their externals.
It is imperative for you to recognise that competition ends once trials are over and it is in your best interest that you encourage others to study and help them if you can in the hope that someone kills their externals.
