The maximum possible study score is 50. Study scores are fitted to a bell curve with a median of 30, which means about half of all students score 30 or above. A study score of 40 or above is very hard to achieve - less than 9% of students are awarded 40+ study scores for each subject!

'Scaling' is the process by which VTAC adjust the raw study scores for each subject, by comparing students' results across all subjects. For example, VTAC's algorithm has determined that students that score raw 30 in Maths Methods tend to average study scores about 35 in their other VCE subjects. So a raw 30 in Maths Methods is scaled to about 35 to make the Methods study score comparable to other subjects, when calculating students ATAR scores.

For most VCE subjects, your internal SAC scores contribute 50% to your study score, and the final exam contributes the other 50%. For VCE Mathematics, the internal SAC scores contribute 40% and the final two exams contribute the other 60%.

'SAC moderation' is the process by which VCAA allocates your SAC grade, by comparing your SAC results relative to the other students at your school, then comparing your school's exam results to other schools.
