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.	International Studies is a degree where you combine courses from fields like economics, history, business, and development to understand global issues and how different countries interact. The iBA option includes a mandatory year abroad at a partner university, immersing you in another culture while continuing your studies, whereas the regular BA keeps you on campus. It suits students who want broader perspectives on world problems rather than specializing in a single discipline, and who are curious about how global systems actually work.	You study both business and science together as a combined honours degree, taking courses in fields like accounting, chemistry, computer science, or biology alongside business and economics. This differs from a straight business program because you develop scientific literacy and research skills, not just business knowledge. It suits people who want to understand how science and data work in real-world business contexts, or who haven't decided between these two interests yet.
