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 teaches you how to manage engineering projects and operations by combining business decision-making with technical knowledge of systems, data analysis, and software. Unlike a straight engineering degree, it focuses equally on the management and optimization side of engineering work, drawing from fields like operations research and artificial intelligence. It suits students who are strong in math and science but interested in leadership roles, problem-solving with data, and working on real problems through mandatory paid work terms.	This program lets you study mathematics while choosing how to apply it — through business, economics, statistics, artificial intelligence, or education. Unlike a pure mathematics degree, you're expected to connect mathematical theory to real-world problems in fields like finance, operations, or data analysis. It suits students who enjoy math but want flexibility to explore where it leads them, rather than committing to one specialty upfront.
