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.	This program combines psychology, biology, computer science, linguistics, and philosophy to study how the mind works and how we think, learn, and use language. Unlike a straight psychology or computer science degree, cognitive science integrates all these viewpoints to understand cognition from multiple angles. It suits people curious about the science of thinking itself, who want breadth across disciplines rather than depth in just one.	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.
