What it is	A Science Non-Honours degree lets you study physical sciences — chemistry, geology, and related fields — without committing to a specialized honours stream. You complete a three-year program with broader course choices and fewer upper-level requirements than an honours degree, giving you flexibility to explore different areas before specializing or applying to professional programs. This suits students who want a solid science foundation, aren't sure which specialization to pursue, or plan to move into medicine, health sciences, or graduate study.	This is a first-year science program that teaches you foundational chemistry, physics, and related subjects before you specialize. Unlike going directly into a single honours program, you spend your first year exploring different branches of physical science, then choose your final degree path — either a pure science degree or a combined science and engineering degree. It suits students who are strong in math and science but aren't yet sure whether they want to focus purely on theory or blend science with applied engineering.	You start your first year studying foundational science — chemistry, physics, and related subjects that prepare you for medicine or specialized science programs. Rather than declare a major immediately, you complete a broad first year, then choose your focus (like biochemistry, physics, or health sciences) once you understand the field better. This suits students who know they want science but aren't certain which direction yet, or who want flexibility before committing.
