I graduated with a bachelor of math advanced (honor) with first class honor from an Australian university with a WAM (weighted average mark) of 93. My university does not have any GPA system.
I am applying for a graduate program in math in US and somewhere in their application, they say:
If you have a GPA less than 3.8, then do not apply.
I do not know if I fall below 3.8 or not. All my grades are HD (High Distinction) per the Australian system. My lowest mark is 88 (out of 100) for a course in real analysis. Other grades vary between 90 and 99. In the Australian system, if you get a mark between 85 and 100, then you get HD grade for the subject.
