Recently though, they seem to be really inaccurate. Prior to 2010 they were fairly on the money, but last year and by the looks of it especially this year, they seem to be a bit off base even for the higher ATARs.The calculators give a pretty good estimate of what you get especially those that are 95+. They are usually at most 0.5 off. Below that they can sometimes be off by 1 ATAR. I got 0.25 lower than what both calculators predicted haha Got my hopes up But then again wasn't expecting it to begin with
