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.	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 combines science study with teacher education, so you earn qualifications to teach science in secondary school while completing your degree. Unlike a regular science degree followed by teacher training, you work toward both goals at the same time, with coursework in science disciplines alongside education theory and practice teaching. It suits students who know they want to teach and want to study science deeply rather than broadly.	This is a broad science degree where you choose from fields like biology, chemistry, physics, computer science, geology, and others. You take foundational science courses in first year, then specialize by selecting which science subjects to focus on. Co-op is available, letting you do paid work terms at science-related employers alongside your studies.
