What it is	This program lets you study science by mixing chemistry, physics, and other fields rather than focusing on just one. You design your own pathway through courses across multiple disciplines, so you might combine chemistry with environmental science or physics with biology depending on your interests. It suits students who want flexibility to explore where different sciences connect instead of committing to a single specialization.	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.
