I am not sure what you mean by raw HSC mark.
The only time that raw marks come up are the raw exam marks - which are the marks actually awarded by the markers.
These marks are added and then aligned. You get told the aligned marks.
Your assessment marks sent by the school may be the raw marks the school determined or adjusted by them in some way. These marks are then moderated by the BOS after the raw exam marks have been aligned. These moderated marks are also given to you.
The average of these aligned and moderated marks are the final HSC marks.
