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.	Life Sciences is a broad study of living organisms, their cells, genetics, and chemistry at the molecular level. You'll take core courses in biology, chemistry, and biochemistry, then choose a focus like microbiology, biotechnology, or human biology depending on your interests. The co-op option lets you alternate between school and paid work terms in research labs, hospitals, or biotech companies, giving you real experience alongside your degree.
