What it is	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.	Engineering is a four-year degree in applied science and problem-solving, with seven specializations: civil, computer, electronic and electrical, geomatics, mechanical, software, and space. The co-op option lets you alternate between classroom semesters and paid work terms at engineering firms, giving you real experience before you graduate. It suits people who want hands-on technical training, enjoy math and physics, and prefer learning through doing alongside theory.	In your first year, you take core math, physics, chemistry, and engineering courses alongside introductory modules in civil, computer, electrical, mechanical, software, and space engineering. This gives you time to explore which engineering discipline suits you before specializing in upper years. The program includes paid work terms, alternating with school, so you gain industry experience while studying.
