UAC compass overestimates your atar by at least 3 points for marks below 78 in English Advanced (1 Viewer)

[coolcat6778]

Explanation:
The UAC compass calculator is extrapolating the graph below 78 from origin (shown as the straight red line) because for some reason UAC couldn't use the whole dataset for their public calculator. However, using the knowledge that all English scale the same as stated by UAC themselves, we know how Advanced actually scales (same as studies and standard) (the extrapolated graphs of each subject look slightly different due to limited datasets, however in actuality they should be identical).

Because it is extrapolating the graph, it over estimates scaled marks (and hence atar) below 78 hsc mark since the curve is significantly concave up below 78. (math advanced knowledge)

This calculator https://atarestimator.streamlit.app/ from https://www.linkedin.com/posts/grah...p&rcm=ACoAAEdlYqYBx3Iby66yKAAsHsYneQxUl__wWpM correctly accounts for this and is probably the most accurate atar calculator
