Scales up
Raw 40 → 44 scaled

Chemistry scales up moderately. The 44 scaled-from-40 reflects a cohort that performs above the VCE median in their other studies — typical for a Unit 3/4 science.

What is a good study score in Chemistry?

In 2025, a raw 30 in Chemistry scaled to 34, raw 40 scaled to 44, and a raw 50 scaled to 50. 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 Chemistry scale up or down?

Scales up. A 40 raw lifts to the mid-40s scaled — a meaningful boost when paired with strong subjects. The 2025 VTAC anchors are listed in the table above. Read how VCE scaling works for what that means in practice for your ATAR.

How Chemistry feeds your ATAR

The scaled study score above is what feeds your ATAR aggregate. Your top four scaled scores (including your highest English) contribute at full value; your fifth and sixth contribute at 10%. See how the ATAR is calculated for the full chain.
