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 Science (General) lets you study science broadly across biology, chemistry, environmental science, and related fields, choosing your own mix of courses rather than specializing deeply in one area. Unlike an honours program, it gives you flexibility to explore multiple sciences without committing to a single major or meeting the tighter requirements of a specialized stream. This suits students who are curious about science in general but aren't yet sure which direction appeals to them most.	Life Sciences is a broad study of living organisms, their cells, genetics, and chemistry at the molecular level. You'll take core courses in biology, chemistry, and biochemistry, then choose a focus like microbiology, biotechnology, or human biology depending on your interests. The co-op option lets you alternate between school and paid work terms in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.
