How the ATAR is built from your scaled scores
Your ATAR is not an average of your marks. VTAC adds up your best scaled study scores to make an aggregate, then ranks that aggregate against every student to give a percentile, which is your ATAR.
The aggregate uses your best English score plus your next three highest scaled scores at full value. Your fifth and sixth subjects then add 10% each. This tool applies that exact method, then reads your ATAR from the official 2025 aggregate table.
Scaled scores, not raw study scores
This predictor needs your scaled study scores. A raw study score of 40 in one subject is not worth the same as a 40 in another once scaling is applied. If you only know your raw study scores, run them through the ATAR scaling calculator first, then bring the scaled numbers back here.
Use it to set a goal
Try different combinations to see what you need for a target ATAR. A small lift in two or three subjects often moves your ATAR more than you expect near the top of the range. To estimate from raw marks in a specific state instead, use your state tool on the ATAR calculators hub.
