Math Circle is a group that meets regularly with the aim of helping high school students practice and develop competition math skills. Weekly meetings occur on campus in January to April of each school year. Students attend lectures on various mathematical topics given by UBC’s excellent faculty and then work on competition-level problem sets.

To learn about the history of Math Circle, click here to visit its page on the UBC Math Department’s outreach website. The Math Circle is currently organized by Professor Dragos Ghioca and student volunteers at UBC. In 2021, the organizers were Henry Xia and Victor Wang.

Math Circle 2012 concluded on April 19th. Please check back in early 2022 for information on next year’s Math Circle. Feel free to take a look at the problem sets from previous years!
