What it is	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.	You study both business and science together as a combined honours degree, taking courses in fields like accounting, chemistry, computer science, or biology alongside business and economics. This differs from a straight business program because you develop scientific literacy and research skills, not just business knowledge. It suits people who want to understand how science and data work in real-world business contexts, or who haven't decided between these two interests yet.	Honours Science is a broad science degree where you choose your major from fields like biology, chemistry, environmental science, computer science, or archaeology. Unlike a general science program, an honours degree requires you to specialize in one subject and complete more advanced courses in that area. It suits students who want a strong grounding in science but haven't yet decided on one specific career path, or who want deeper knowledge in a particular field.	This program lets you earn two degrees at once: a business administration credential covering accounting, finance, and entrepreneurship, plus an international studies degree in history, geography, or environmental studies. Unlike a typical business degree, you're required to complete a co-op work term, which gives you practical experience alongside classroom learning. It suits students who want both solid business training and deeper knowledge of global issues or a second subject area.
