Your highest listed choice is considered first when you indicate more than 1 Brock program on your application. If you are not eligible for your first choice, your subsequent choices will be considered in your indicated order of preference. In most cases: If you apply to only 1 Brock program but do not qualify, you will be considered for an alternative or related program. If you apply but are not admitted to a co-op program, you will automatically be considered for the regular, non-co-op program.

What it is	Computer Science I is an introductory computer science program where you learn programming, algorithms, and core computational concepts. It differs from some other programs because it includes a mandatory co-op component, giving you paid work experience in tech roles alongside your studies. This program suits students who want hands-on industry experience early and are curious about whether computer science matches their strengths before committing to upper-year specializations.	Computer Science at Western teaches you how to write programs, build software systems, and solve problems using computers and code. You choose a focus — such as game development, managing information systems, or engineering robust software — based on your interests. The program includes paid work terms alongside your studies, letting you apply classroom learning in real jobs and build professional experience before you graduate.	You study how to use data and statistical tools to solve problems in finance and banking. The program combines computer science, mathematics, and finance, so you learn to build models and analyze trends rather than just learning finance theory or coding separately. It includes paid work terms with employers, giving you real experience before you graduate. This suits people who want a technical, analytical career in financial institutions or companies that rely on data to make decisions.
