The 2014 Putnam examination was given on Saturday, December 6, 2014; UBC had 18 students participate, even on a day when final exams were being given. Indeed, four of them took final exams right after the Putnam—stoically solving problems from 7 AM to 7 PM!
Putnam practice sessions are held every Tuesday from 12:30-2:00 PM during the fall semester; they will start again in September 2015. The faculty advisor is Greg Martin. The math department's Putnam FAQ has more information, as does the official Putnam web site.
