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.	Honours Science is a broad science degree where you choose your major from fields like biology, chemistry, environmental science, computer science, or archaeology. Unlike a general science program, an honours degree requires you to specialize in one subject and complete more advanced courses in that area. It suits students who want a strong grounding in science but haven't yet decided on one specific career path, or who want deeper knowledge in a particular field.	You study core business subjects like accounting, finance, marketing, and human resources, alongside economics and psychology. This program includes a co-op stream, meaning you alternate between classroom terms and paid work terms at companies, giving you real workplace experience alongside your degree. It suits people who want practical business skills and prefer learning by doing, not just theory.	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.
