What it is	Computer Science I is an introductory computer science program where you learn programming, algorithms, and core computational concepts. It differs from some other programs because it includes a mandatory co-op component, giving you paid work experience in tech roles alongside your studies. This program suits students who want hands-on industry experience early and are curious about whether computer science matches their strengths before committing to upper-year specializations.	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.	Social Science is a broad study of how people, societies, and economies work. You choose a focus like economics, anthropology, history, or business studies, then take courses across that field. Western offers this as either a BA or BSc depending on your focus, and you can do it with co-op, meaning you alternate between school terms and paid work placements in your field.	Science One is a general first-year science program that lets you explore multiple science disciplines — biology, chemistry, physics, computer science, and others — before committing to a specific major. Unlike entering directly into a single science program, you take a broader range of foundational courses to discover which field best suits you. It works well for students who are interested in science but unsure which specialization to pursue.
