What it is	Actuarial Science is the study of risk and uncertainty using mathematics, statistics, and business analysis to help insurance companies, pension funds, and other organizations make financial decisions. Unlike a pure mathematics degree, this program focuses on applied problem-solving for real-world financial scenarios. The co-op option lets you work in the field while studying, giving you practical experience alongside your coursework. This program suits people who enjoy mathematics and statistics, think logically about complex problems, and want a career with strong technical foundations and professional prospects.	You study computer science and mathematics together over five years, learning how to write code, analyse data, and solve problems using mathematical theory and statistical methods. Unlike a single major, this double degree gives you depth in both fields so you can build algorithms and understand the theory behind them. It suits people who want flexibility between pure mathematics and applied programming, and who value alternating work terms with their studies.
