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 at Brock is a four-year degree where you study programming, algorithms, software design, and computing theory. The co-op option means you alternate between semesters of study and paid work terms at tech companies, giving you real workplace experience alongside your coursework. It suits people who want technical depth and prefer learning through hands-on projects and industry internships.	Environmental sciences combines biology, chemistry, economics, and Earth systems to understand how environments work and how human activity affects them. The co-op option lets you alternate between study terms and paid work placements with environmental organizations, government agencies, or companies, giving you real experience alongside your degree. This program suits people who want practical skills in environmental problem-solving and prefer learning through both classroom study and workplace application.	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.
