What it is	This program teaches you the science behind how the human body works, how diseases develop, and how medicines treat them. You study human biology, pharmacology, and related medical sciences rather than practising medicine itself. The co-op version includes mandatory work terms at healthcare or research organizations alongside your coursework, letting you test whether this field suits you before committing to further training.	You study how Earth's climate and environment work, using chemistry, physics, and geography to understand weather systems, ecosystems, and human impacts. This program combines natural science with social geography, so you examine both the physical causes of environmental change and how people and communities respond to it. It suits students curious about climate science who want hands-on experience through co-op placements alongside their coursework.	You study chemistry, physics, astronomy, or geology at an advanced level, choosing your focus after first year. This program includes a co-op option that lets you work for employers in research, industry, or government between school terms. It suits students who are curious about how matter, energy, and natural systems work and want both hands-on lab experience and real-world work placements.
