Regional Finals
Judges’ Report
The judges are pleased with the results. Our hope was that the contest allowed competitors to push themselves and to spend the whole five hours solving interesting questions. I think we achieved this. All the teams solved at least four problems, and the top team solved eleven. This shows great efforts at both the lower and upper ends of the scoreboard. Further, there was an exciting (and tight) race for second place, which was fun to resolve after the final hour. Congratulations to all our Regional Finals teams!
