It's easy to get confused.
There are two paths followed by your raw marks:
raw marks -> scaling -> scaled marks -> UAI
raw marks -> aligning -> aligned marks -> BOS Record of Achievement
An 'HSC mark' (where 'aligned' or 'scaled' hasn't been specified) is generally taken to mean the aligned HSC mark that appears on the actual certificate awarded by the Board.
The term 'scaling' usually refers to the process used by the Technical Committee on Scaling when calculating UAIs.
The term 'aligning' usually refers to the process used by the Board when adjusting your marks to course standards. For all intents and purposes, it is also a form of scaling - the new label is a lame bureaucratic attempt to abolish scaling, and also serves to (supposedly) avoid confusion.
