Do the compulsory subjects in the B.Biomed cover the prerequisites for the M.D?
Yep
Wait - at UoM they drop your two lowest scores when calculating GPA?! O.o
It's the two worst subjects within the first 200 points (i.e. the first two years,) of the degree. But, as others have said, there's not one way to calculate your GPA at unimelb. It depends on whatever you're applying to. Most people use SGPA as it's semi-sanctioned by the university (plus, as simpak says, it makes you look better.)
Enrolling in Honour (technically a 'new degree') has made me realise again how awful the unimelb enrolment system is. Why do I need to 'reconfirm' my cultural details? It's not like I change the language I speak every year.
