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 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.	You study how chemicals and biological systems work together to solve real-world problems, learning biochemistry and chemical engineering side by side over five years. This dual degree goes deeper than choosing one field: you gain skills in both the science of living systems and the design of industrial processes. It suits people who want flexibility to work in pharmaceuticals, biotechnology, or chemical manufacturing, and who value alternating study terms with paid work placements through co-op.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
