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.	You study the mathematical and programming foundations of artificial intelligence and data analysis, including how to build systems that learn from large datasets and make predictions. This program goes deeper into AI and statistics than a general computer science degree. It suits people who want to work with machine learning, data analysis, or AI systems and are comfortable with both math and coding.	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.	This program combines science courses with business studies, so you study both scientific subjects like chemistry, biology, or computer science alongside accounting, management, and economics. Unlike a straight science degree, you gain practical knowledge of how science-based industries operate and how to manage projects or companies. It suits students who want a science career but also care about the business side — whether that's starting a science company, managing research teams, or working in science-related industries.
