Like many other HSC students, Christian is looking forward to the time-honoured tradition of burning his notes after exams end. "I'm collecting all the exam papers, too, which I'll probably end up burning," he said.

Christian is unsure what career he wants to pursue; for now he is too distracted choosing which University of Wollongong early-entry offer to accept. "I'm trying to pick between primary education and a business degree, but, depending on my ATAR, I might try for a double law and business degree."

His advice regarding studying for exams included removing digital distractions. "If you're studying on a computer don't have the internet connected, and turn off your Wi-Fi and mobile phone," he said.
