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 four-year degree in computer science, covering artificial intelligence, software engineering, and core programming concepts. You can choose to add a co-op stream, which means you work semesters at tech companies alongside your studies, building real workplace experience. It suits people who want to learn software development with the option to gain paid industry work experience before graduating.	Engineering at Western teaches you to design and build solutions to practical problems using mathematics, science, and materials. You choose a specialization like software, mechanical, civil, or chemical engineering, or study general engineering first before deciding. The program includes co-op work terms, so you alternate between classes and paid jobs with employers, giving you real experience alongside your degree.
