At Macquarie, they (internally) operate under a different system from most other universities in NSW.
Hd & D = 4
Cr = 3
P = 2
PC = 1
F = 0
Therefore a Macquarie GPA would lie between 0.00 and 4.00.
In other university GPA systems, a GPA of 5.00 would equal to a Credit average, where
Hd = 7
D = 6
Cr = 5
P = 4
F = 0
You can't quite say a Macquarie GPA of 3 is equal to another university's GPA of 5 because Macquarie considers Hd and D one and the same. Consider at Macquarie, a person gets a Hd, D, D, Cr, they'd have a GPA of 3.75 - "almost D" average. Whereas at another university a Hd, D, D, Cr would give them a GPA of 6 - a D average.
