Estimate your Study Score (0–50) from SAC + exam marks, using VCAA's mean-30/SD-7 model
Based on VCAA's published standardisation model. Real-world distributions aren't perfectly smooth at the extremes (very few students score above 47), so treat scores above ~45 as increasingly approximate.
Indicative only. Every VCE study design publishes its own exact SAC/exam weighting — always check the specific figure for your subject at vcaa.vic.edu.au.
Estimates only. Your real Study Score depends on VCAA's statistical moderation of your SAC marks against your school's exam performance and the full state cohort's results — data no outside calculator has access to. Not affiliated with VCAA or the VTAC. For official information, see vcaa.vic.edu.au.
A VCE Study Score runs from 0 to 50 and is standardised so the state cohort for each subject has a mean of 30 and a standard deviation of about 7. Your raw School-Assessed Coursework (SAC) and exam marks are combined using that subject's official weighting, then statistically converted onto this scale. A score of 30 is the state median; a score of 40 or more typically places you in the top 9% of students taking that subject. Because the real conversion depends on VCAA's statistical moderation of the full state cohort, any outside calculator — including this one — can only give an estimate.
Our free VCE Study Score Calculator helps Victorian students estimate their Study Score for each subject from their SAC and exam marks. Add your subjects, choose the SAC/exam weighting that matches each study design, and see an estimated Study Score, percentile, and a visual of where you sit on the state-wide bell curve.
Because every subject's Study Score is standardised to the same mean (30) and spread (SD ≈ 7), a Study Score tells you where you rank against other students in that specific subject, not a percentage or a raw grade:
Your Study Score (0–50, mean 30) measures your performance within your subject, relative to everyone else who took that same subject. Your scaled study score is a separate, later step used for ATAR purposes — VTAC adjusts study scores between different subjects based on the relative academic strength of each subject's cohort, so that subjects can be fairly compared against each other. A Study Score of 35 in one subject is not automatically worth the same in your ATAR aggregate as a Study Score of 35 in a different subject. For that scaling step, see our Subject Scaling Calculator and VCE ATAR Calculator.
VCAA does not publish a formula that converts a specific raw percentage directly into a Study Score, because the real conversion depends on statistical moderation against the entire state cohort's actual results each year — data that isn't available outside VCAA. This calculator uses the well-documented mean-30/SD-7 standardisation model as its foundation, combined with a reasonable approximation of how raw marks typically spread across a VCE cohort, to give you a genuinely useful planning estimate rather than a definitive number.
Your SAC marks are statistically moderated against your school's exam results, then combined with your external exam marks using each subject's published weighting. VCAA converts this combined raw result into a Study Score from 0 to 50, standardised so the state cohort has a mean of 30 and a standard deviation of approximately 7.
A study score of 40 typically places a student in approximately the top 9% of the state cohort for that subject. A study score of 45 is roughly the top 2%, and 50 is awarded to only a very small number of students statewide.
A study score of 30 is the state median for that subject — roughly half of all students taking it score above 30 and half score below. It reflects an average result relative to everyone taking that specific subject.
It depends entirely on the subject. Each VCE study design publishes its own SAC-to-exam weighting, commonly ranging from around 50/50 for many humanities subjects to roughly one-third SAC and two-thirds exam for subjects with two exams. Always check the specific weighting for your subject on the VCAA website.
No. Your Study Score measures your performance within your subject, standardised to mean 30. Your scaled study score is a separate figure calculated later for ATAR purposes, adjusting between subjects based on the relative strength of each subject's cohort.
