What it is	You study the theory and practice of building software, designing systems, and solving problems with computers. Carleton's program lets you focus on specializations like artificial intelligence, games, or software engineering, and includes a co-op stream where you alternate between classroom and paid work terms. This suits students who want hands-on industry experience alongside their degree and are interested in both the technical and applied sides of computing.	Environmental Geoscience is the study of Earth's physical systems — rocks, landforms, water, and climate — combined with how human activity affects and depends on the environment. It differs from pure geology because it emphasizes the interactions between natural processes and people, drawing on geography and environmental science alongside earth science. It suits students curious about how landscapes form and change, and interested in solving real-world problems like pollution, resource management, or climate impacts.	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.	You study the natural systems that support life on Earth — combining biology, chemistry, geology, and geography to understand ecosystems, environmental problems, and how living things interact with their physical surroundings. This pathway is structured to integrate multiple science disciplines rather than focus narrowly on one, and it includes mandatory co-operative work terms where you apply classroom learning to real environmental jobs. It suits students curious about how nature works across scales, from molecules to landscapes, who want hands-on experience before deciding on a specific environmental career.

Ranges are what each university publishes, not guaranteed cutoffs, and limited-enrolment programs often admit above them. Confirm anything you are about to act on with the university; each column links to its source.
