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 chemical engineering — how to design and optimize chemical processes and manufacturing at industrial scale — and computer science, learning to build software and computational systems. The five-year structure and mandatory co-op terms give you paid work experience alongside your degree, letting you apply both skillsets in real industrial settings. This suits students who want to bridge chemistry and coding rather than choose one, and who value hands-on experience while earning.	Computer engineering combines the design of computer hardware with the software that runs on it. You'll study circuits, processors, programming, and systems that integrate both. The co-op stream lets you alternate between classroom and paid work terms at tech companies, giving you real industry experience alongside your degree, which sets it apart from the straight four-year option.	You study how to design and operate chemical processes that transform raw materials into useful products — everything from pharmaceuticals to plastics to fuels. Chemical engineering combines chemistry, physics, and math to solve real industrial problems at scale. The co-op stream lets you alternate between classroom terms and paid work terms at companies, giving you direct experience in the field while you study.
