Basically it's your scaled HSC mark that is used. The scaled HSC mark is the result of scaling the RAW HSC mark.
The mark you saw today is the result of a process by the Board of Studies called "aligning" which changes your mark to fit a set of standards achieved.
To attain the UAI and your HSC marks, the 2 procedures used are independent of each other except for the fact that they both use your RAW HSC mark.
so they dont use what we saw today? or they take the hsc mark today and scale it further either up or down. what does aggregating and ranking, equipercentile mapping all mean? im hoping the marks get scaled further because right now the hsc marks given today arent good enough.
