Common mistakes with Australian History scaling
The first mistake is chasing scaling instead of results. Scaling only helps if you score well. A strong study score in Australian History beats a weak one in a higher-scaling subject.
The second is thinking one subject decides your ATAR. Scaling changes each score by a few points, then your best scores are combined. Strong results across all your subjects matter far more than the scaling of any single one.
