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 protect computer systems and networks from cyberattacks by learning programming, software design, and artificial intelligence techniques. Unlike a general computer science degree, this program is built around real-world security problems and includes a co-op work term, so you apply what you learn in actual jobs while still studying. It suits people who want hands-on technical experience and are interested in the growing field of protecting digital information.	You study both chemical engineering — how to design and optimize chemical processes and manufacturing at industrial scale — and computer science, learning to build software and computational systems. The five-year structure and mandatory co-op terms give you paid work experience alongside your degree, letting you apply both skillsets in real industrial settings. This suits students who want to bridge chemistry and coding rather than choose one, and who value hands-on experience while earning.	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.
