GPA in Australia:
Distinction grades are obtained when you get a GPA above 3.5 for a four-grade point average and above 6 for a seven-grade point average. Depending on your institution and grades, you can either get a High Distinction for a 7 and 4 GPA or a Distinction if you get anything lower than 7 and 4 but higher than a 3.5 and 6 GPA.
