Bachelor of Science

Improve The Ecosystems Of Life

Explore the science of life, with a Bachelor of Science (B.Sc.) from U of G. Accept the challenge to discover new ideas about our world. From modelling the behaviour of ecological systems to defining atomic behaviour, establish the knowledge, abilities and the drive to improve our world for tomorrow. 

Access some of the world’s most respected research scientists and teachers, and facilities that match. Build a solid foundation of seminar and lab experiences in the biological, physical, chemical, computing and mathematical sciences. First-year core courses will enable you to explore and transfer between majors in biological or physical sciences. 

Refine your critical thinking and communication skills, strengthen your knowledge and application of scientific methods and techniques and foster both personal and professional integrity to help you achieve your career goals in fields such as rehabilitation sciences, education, research and law.

Note: students may need to incorporate additional prerequisite courses to meet admission requirements for postgraduate programs depending on their major.
