Hey guys,
Next year I will continue with my second year of a bachelor of commerce/bachelor of science degree and have contacted buseco about wanting to complete a double major for the commerce part of my degree. All they said was that there is a maximum of 16 units I can take, hence I can only complete one major. I have figured out that I would need 20 to complete the double major since I have some subjects that overlap between my other intended majors.
So I was just wondering, how can I be exempt from this 'maximum of 16 units' rule? Im assuming there would be a minimum grade average needed, does anyone know what it would be?
This may be a bit far-fetched but if this exemption isn't possible (although I have seen other threads that say it is), is it possible to be enrolled in two courses at once? (The course I'm doing now and another bachelor of commerce majoring in the second major)

Any help would be appreciated
Thanks!
