Still around 94 as others have said. Most people tend to really go into HSC. It's not just him having a wake up call, it's alot of people! Because alot of people tend to do try harder in the HSC it's also harder to impress markers, so really it depends how much more he's putting into HSC. Anyone aiming for 98+ though usually works consistently throughout the year and already has that goal in mind through the year. Not just getting a wake up call unfortunately. 15 ranks from a 300 position doesnt do too much either,it usually means the bottom cohorent has moved to average up with everyone else, there's always a few who get a good ATAR but in schools between 200-300 only 1-3 each year tend to get 98+
