For most Year 12 students in Australia, the ATAR looms large. It's often misunderstood: it isn't a mark, it doesn't measure your worth, and it's only one way into university. This site brings together independent, plain-language guides to how the ATAR works, how to study well, and what to do after results, with official sources on every page.
Explore the guides
- ATAR explained What the ATAR is, how scaling works, how each state calculates it and common myths.
- Study Study timetables, exam preparation, managing exam stress and healthy sleep habits.
- After results Selection ranks and adjustments, course entry data, pathways and preferences.

A rank, not a mark
UAC describes the ATAR as a number between 0.00 and 99.95 that indicates a student's position relative to all students in their age group. It runs in steps of 0.05, so an ATAR of 80.00 means you placed about 20% from the top of your age group, not that you scored 80%. UAC notes the average ATAR is usually around 70.00, because students who stay on to receive one are a smaller group than the whole age group. ATARs are designed to be equivalent across states.
How it's calculated
Each state's admissions authority scales subject results so different subjects can be compared fairly, adds the best scaled results into an aggregate and ranks the aggregates. The rules differ: UAC counts 10 units including 2 of English, VTAC counts an English subject plus the next best three with 10% of two more, QTAC counts the best five eligible inputs, SATAC the best 90 credits and TISC the best four scaled scores plus 10% bonuses for certain subjects.
Why we don't predict ATARs
Despite our name, we don't offer an ATAR predictor. SATAC says there's no accurate way to predict an ATAR in advance and doesn't recommend online prediction tools, because scaling depends on each year's students. Instead, our free planner helps with the things you can control: planning study and understanding selection ranks.
Study well
Active revision, such as practice questions, self-testing and past papers, spread over time, usually beats rereading notes and cramming. ReachOut recommends a realistic study schedule with regular breaks and time for things you enjoy. healthdirect says teenagers need 8 to 10 hours of sleep a night, and national guidelines recommend at least 60 minutes of physical activity a day for young people.
After results
UAC explains that most courses select on a selection rank: your ATAR plus any applicable adjustments. QTAC says adjustment factors don't change your ATAR, and institutions limit how many points can be added. VTAC explains that lowest selection ranks aren't set in advance, so last year's figures are only a guide. And if things don't go to plan, SATAC reminds students that the ATAR is just one pathway.

Looking after yourself
Year 12 can be stressful. If stress is affecting your sleep, relationships or wellbeing, talk to someone you trust, your school counsellor or your GP. Kids Helpline (1800 55 1800) and Lifeline (13 11 14) are available 24/7. In an emergency, call 000.
About this site
This web address was once home to an independent ATAR estimator and study-tips site, which later closed. ATAR Calculator is a new, independent site with original content and no connection to that site or any previous operator. We aren't an admissions centre, curriculum authority, school, university or tutoring company, and we're not affiliated with UAC, VTAC, QTAC, SATAC, TISC or any institution. We never invent statistics, cut-offs, prices, quotes or reviews, and our guides are general information, not careers, educational or medical advice.
How we work
Every guide is written in our own words from official sources, including the state admissions centres, government health guidance and youth mental health services. We link to those sources at the end of each page and review guides regularly. Read our editorial policy for details, or contact us with corrections.
