On average, what is the margin of errors for these ATAR calculators ( namely Matrix)
im guessing plus or minus 1 ATAR point... it cant be more right
Also, do these calculators tend to over or under estimate?
What does percentile out of 100 actually means when using matrix calculator?
If we put 60 percentile does it mean were in the top 40 percent of the state?
