Bachelor of Science

Improve The Ecosystems Of Life

Accept the challenge to discover new ideas. From modelling the complexities of ecological systems to defining atomic behaviour, you will gain the knowledge, the skills and the drive to improve our world for tomorrow. Study in new labs with some of the world's most respected research scientists and discover new ideas about our world. 

Not sure if your passions lie in theoretical physics or neuroscience? Are you thinking food science is your end goal but then you discover nutritional and neutraceutical sciences? Is microbiology with a minor in biotechnology your path? Our Bachelor of Science majors are flexible. With a common first year, introductory courses will enable you to explore and find where your passions lie.

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