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 at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	Commerce is a broad business degree covering accounting, finance, management, and marketing alongside core business concepts. You'll study how organizations operate financially and strategically across different functions. It suits people who want a flexible business foundation before specializing, rather than committing to accounting or finance alone from day one.
