Algorithmics (HESS)
Algorithmics (HESS) is one of VTAC's most generously scaled studies. A raw 40 lifts to 47 scaled — meaningfully higher than almost any other Unit 3/4 subject — because the cohort is academically heavy and the assessment tightens at the top.

Algorithmics (HESS) vs Foundation Mathematics
What is a good study score in Algorithmics (HESS)?
In 2025, a raw 30 in Algorithmics (HESS) scaled to 38, raw 40 scaled to 47, and a raw 50 scaled to 51. A scaled mid-30s lands you in the upper third for ATAR contribution. A scaled 40+ in this subject is strong, and 45+ is exceptional.
Does Algorithmics (HESS) scale up or down?
Scales up strongly. A 40 raw becomes 47+ scaled. Among the most generous scaling in the entire study list. The 2025 VTAC anchors are listed in the table above. Read how VCE scaling works for what that means in practice for your ATAR.
