So, after now doing past HSC papers, i see that many of the questions in my biology trial exams were directly ripped straight from past HSC papers, around 60% of questions from my trial were simply the exact same question with no tweaks made taken from last 2015's and 2016's papers. I was just wondering if this was allowed, seeing as anyone could open the marking criteria and get an unfair advantage for over half the trial paper?Also aren't HSC exams copyrighted, therefore making it illegal for my school simply to take questions straight out of them? I'm not sure what to think and so have come to ask you all on your opinions. Thanks in advance.
