Math Circle

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. This year, the organizers are Henry Xia and Victor Wang.

Math Circle is held from 5-7pm PST on Mondays on Zoom, starting January 18th. If you are a student interested in joining Math Circle, please email or for the Zoom link.
