At this point in the year, the question on everybody’s lips is the same – what’s my ATAR going to be? Here to provide the answer comes every student’s favourite post-exam resource: the Matrix ATAR calculator. But hold on a sec. There’s another question that needs asking: just how accurate is the Matrix ATAR calculator? Thankfully, that’s one we can help you out with.

All you need to do is plug your final exam results into the calculator and it will give you back its estimate of what your final ATAR will look like. Because your final exam results will be scaled and your internal school ones won’t, you’ve got to use your final exam results or else the estimate won’t have a very good chance of being close.

We won’t go into the nuts and bolts of how scaling works, but the basic premise is that a subject is scaled in terms of value according to how well the students taking that subject that year do in their other subjects. The key phrase there being “that year”.

The scaling data changes every year and is only released at the same time as the ATAR results. As a result, ATAR calculators are relying on old data to make their calculations. The estimate you get from them is what your ATAR would have been had you been graduating with those results last year.

The scaling is unlikely to change enormously each year, so the estimate you get from the calculator is probably going to be close enough to what your final ATAR will look like. But at the end of the day, it’s just that – an estimate. Unfortunately, there’s no way you can say with complete certainty that the number generated by the calculator is going to end up being the number you get in December.

Using a matrix calculator, you is capable of doing the necessary calculations with matrices, resulting in the desired answer and an in-depth solution sequence. The

matrix calculatorallows you to perform businesses with an individual matrix or solve complex expressions with several matrices at once.
