the question may as well have said:
" Throughout the duration of your course, you have studied texts in time and how context shapes values. A week ago, you memorised a generic essay. Please regurgitate ."
well considering that your trials are about 30-40% of the 50% internal ( ie. 15-20% of final) as opposed to the 50% of the external exams
the hsc exams are worth about 2-3 times more than the trial
dw you can still get 90 if you do well in them
