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.	Computer Science Co-op is a four-year program in which you study the theory and practice of computing, programming, and problem-solving with code, alongside paid work terms in the field. The co-op requirement means you alternate between semesters of classes and semesters working at companies, giving you real workplace experience before graduation. This suits people who want to test out computing careers early and build a professional network while earning and learning.	You study the design, development, and theory behind computer software and systems. In the co-op stream, you alternate between classroom terms and paid work terms at tech companies, giving you practical experience alongside your degree. This program suits people who want to build real-world coding skills early and explore whether they prefer software development, artificial intelligence, games, or other computing specializations while earning money.
