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 run and launch businesses while learning environmental science and sustainability principles. This combines business skills with ecological knowledge, so you understand both profit and environmental impact. The co-op requirement means you alternate between classroom and paid work terms, giving you real workplace experience in green business and sustainability roles. It suits people who want to work in business but care about environmental problems.	You study business fundamentals across accounting, finance, marketing, human resources, and information systems. The co-op option lets you alternate between classroom semesters and paid work terms at companies, giving you real experience alongside your degree. This suits students who learn better by doing and want to build a professional network before graduating.
