I am accelerating my HSC for maths ext 1 this year and my mark will be out of 50 counting for one unit. But next year I'm going to do maths ext 2, meaning my ext 1 mark will then count for 2 units and be out of 100. If I get a mark of 47/50 in maths ext 1, will that count for 94-95/100, or 93-94/100 for my HSC and ATAR?
