The BCC is a problem solving contest with a focus on computational and logical thinking. Questions are inspired by topics in computer science but only require comfort with concepts found in mathematics curriculum common to all provinces. Connections to Computer Science are described in the solutions to all past contests.

Contest Registration Information

Schools can register for contests online by the deadline. View fees.

Schools that have not registered for previous contests are encouraged to participate, and can start by filling out a New School Application form.

Contest Preparation

The BCC exposes students to a new subject and way of thinking so there isn't a need to prepare for the contest. However, you can get a feel for the style of the problems by viewing past contests and these sample questions.

Results and Recognition
