Biology
Biology sits in the middle of the VCE scaling distribution. A raw 40 becomes 41 scaled, putting it broadly in line with where students enter the assessment.

What is a good study score in Biology?
In 2025, a raw 30 in Biology scaled to 31, raw 40 scaled to 41, 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 Biology scale up or down?
Scales evenly. Raw and scaled scores stay close — what you earn is roughly what you keep. 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 Biology 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.
