I'm about to start at USyd for a bachelor of commerce in management (major) and marketing (minor). In the future, I'm looking to work as an executive or marketing manager, or something of the sort. How would employers see my degree, and do grades matter? In addition, is there a demand for someone with my degree, or would be "useless" like how some people view arts degrees? I'm also planning to go for an MBA after graduating, English is my first language (with French as my second) and I have fairly decent people skills, for more context.

Sorry if the answer to these questions are painstakingly obvious, I'm Canadian and things work differently here (grades don't matter, there aren't many management courses, etc.) And yes, I did look it up but most of the answers were for Finance/Econ/Accounting. Thanks in advance!
