Students register for the 2023 competition individually. See the main page for the links for information and the registration. 

We are not providing sample exam questions but you might want to try some of the older University of Toronto Biology Competition exams for practice and to give you a rough idea of the level of knowledge that is expected. The CBO exam will require detailed biological knowledge and will require you to apply your knowledge in unfamiliar contexts. Campbell Biology remains an excellent text to help you study.
