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.	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.	Life Sciences is a broad study of living organisms, their cells, genetics, and chemistry at the molecular level. You'll take core courses in biology, chemistry, and biochemistry, then choose a focus like microbiology, biotechnology, or human biology depending on your interests. The co-op option lets you alternate between school and paid work terms in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.
