What it is	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.	A Bachelor of Administration or Commerce teaches you core business skills like accounting, finance, management, and human resources, along with how organizations actually operate. The BComm adds a stronger focus on accounting and financial analysis compared to the BAdmin. Both programs include a co-op work term, so you alternate between classroom and paid work at real companies, building experience while you study. This suits people who want practical business skills, like working with numbers or managing people, and who value learning on the job.	This program lets you earn two degrees at once: a business administration credential covering accounting, finance, and entrepreneurship, plus an international studies degree in history, geography, or environmental studies. Unlike a typical business degree, you're required to complete a co-op work term, which gives you practical experience alongside classroom learning. It suits students who want both solid business training and deeper knowledge of global issues or a second subject area.
