What is an ATAR calculator?

An ATAR calculator is an online tool to help you estimate your ATAR or HSC success.

鈥淎TAR calculators can do one of two things,鈥� explains Professor Jacqui Ramagge, Head of the School of Mathematics and Statistics at the University of Sydney. 鈥淭hey can estimate your ATAR from your HSC marks, or they can estimate the HSC marks you need to obtain a given ATAR.鈥�

鈥淭he calculators work on historical data. Typically, they try to tell you how you might have done if you had been in a previous cohort.鈥�

While ATAR calculators 鈥� sometimes called 鈥榬everse calculators鈥� 鈥� can be useful to figure out where you are in comparison to where you need to be to get into your dream degree, they are not a perfectly accurate predictor. You should use them as a rough guide and a study motivation, not an exact science.

How do ATAR calculators work?

There are two ways to use ATAR calculators:

1. Work backwards: ATAR -->聽marks

Start with your desired ATAR, then choose the subjects you鈥檙e studying in order to find the goal marks you need for each subject to achieve your desired ATAR. You can then compare your current marks with your target marks for motivation to boost your current percentages and focus on particular subjects in which you need improvement.

2. Work forwards: marks -->聽ATAR

Start with the subjects you鈥檙e studying, then log your last exam results to estimate the ATAR you鈥檙e predicted to achieve. By using past exam marks as predictors, you can track how much improvement you need to make to reach the ATAR you need to get into your first preference university course.

Where is the data coming from?

鈥淎TAR calculators typically take historical ATAR data 鈥� which is freely available on the 聽(pdf, 1.4MB)聽鈥� and use it to estimate the ATAR you would have got in 2018 with the results that you have now.鈥�

鈥淎ll ATAR calculators produce an estimate. None of them can actually calculate your ATAR. The ATAR calculation changes every year because it uses the marks of every student in the state in every subject they took as part of the calculation of your ATAR. The ATAR calculators don鈥檛 have access to that information. All they can do is estimate using the data that has been made public 聽from the previous year.鈥�

The estimates that ATAR calculators provide are rough, since they don鈥檛 take into consideration that changes year to year, or access to admissions pathways, like our (EAS). The numbers you鈥檝e put into the calculator are only your school marks 鈥� the calculations don鈥檛 include your external exam marks, which may be significantly higher or lower than your averages.

A calculator that produces a high ATAR or low target subject marks may also make you complacent - so don鈥檛 take those current percentages for granted.

What should you do instead?

Professor Ramagge notes that 鈥淭alent is overrated. Hard work is what makes the real difference.鈥�

Putting in the hours is the best way to guarantee success. Listen to our聽study music playlists, read our聽exam tips聽and don鈥檛 forget to聽update your preferences聽before the deadline. Our聽#studygoals聽website has everything you need to know to get you through the HSC and beyond.

Aside from study, ensure you聽keep your mind and body healthy聽throughout exams.

鈥淭he value of rest is well known in educational circles,鈥� says Professor Ramagge. Keep up your positive habits: putting down the books to play sport, stay dedicated to hobbies, and remaining connected to friends and family will also pay dividends towards ATAR success.

Consider courses with a Guaranteed Entry聽

Instead of trying to game the system by guessing your ATAR before exams, focus on your plan of attack for after you receive your ATAR. Once you know your achieved ATAR, look into whether it matches or exceeds the Guaranteed Entry聽selection rank聽needed for admission to your courses of interest. If you achieve the guaranteed rank and place Sydney as your first preference, you will be made an offer through UAC. If you've just missed the guaranteed rank, seek information on your options available through our聽admission pathways聽or look into options for transferring courses.

A final tip from our ATAR expert? 鈥淭ake the highest level of Maths and English that you can.鈥�
