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	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.	Earth Sciences is a study of rocks, minerals, Earth's structure, and environmental systems — how the planet works and how humans interact with it. The program includes a co-op work placement component, meaning you alternate between classroom study and paid work terms at companies or organizations in geology and environmental fields. It suits students curious about natural systems and interested in learning through hands-on experience in the workplace.	You study how the natural world works alongside the human systems that affect it. The BES focuses on environmental policy, conservation, and sustainability through social and geographic lenses, while the BSc emphasizes the physical science side: geology, ecology, and environmental processes. Both paths suit people interested in solving real environmental problems through either policy and community work or scientific research and analysis.	Social Sciences is the study of how people, societies, and economies work. You choose from nine subject areas including anthropology, economics, history, law, geography, politics, and sociology, and can combine them however you want rather than following one fixed path. This program suits students curious about human behaviour, institutions, and the world around them who want flexibility to explore multiple disciplines before specializing.
