Thank you all who joined us for the Woburn Challenge 2015-16 on-site finals this afternoon! After an unbelievably tight race, Richmond Green Secondary School managed to edge out the valiant competition from Don Mills Collegiate Institute (by a mere 1 point within the last 6 minutes of the contest!) to ultimately secure 1st place in the senior division. Meanwhile, Thornhill Secondary School clinched their own champion spot in the junior division. Though this was arguably our toughest contest of the year, we still believe that there was something there for everyone.

Thanks to all of you who took part in round 3, new and returning competitors alike! This round proved to be a bit rougher than usual, both on your end and ours. To start, there were no perfect scorers in either division. Although the first three problems of both divisions had many wonderful full and partial solutions, the last problems seemed to have perplexed everybody. Indeed, getting 100% on either of them them required a fair bit of tricky preprocessing. On the other hand, we also did run into some issues with the problem statements and test data. The issues have all been addressed in comments to the corresponding problems on the judge. Although we strongly believe that these issues had a negligible effect on the overall results, we nonetheless promise to be more careful in the future.
