I discovered that Matrix had a reverse ATAR calculator where you can type in the ATAR you want and it'll display the HSC marks you'll need. So I typed in the ATAR I wanted along with my subjects and when it showed the marks I needed, I was surprised that it wasn't as high as I expected. Then I typed those marks into another ATAR calculator and got a much lower mark. O__O" How does the Matrix ATAR calculator work??
