Concept
The percentage uniform mark (PUM) is the exact mark reported on your Statement of Results.
It is a standardized score that indicates your position within a grade band, regardless of the difficulty of the specific paper.
Mechanism
PUM is derived by mapping your raw mark to the grade boundaries.
Data
