USACO 2019 February Contest, Gold
The gold division had 874 total participants, of whom 734 were pre-college students. This particular contest was quite challenging, and as a result, all competitors who scored 650 or higher on this contest are automatically promoted to the platinum division. Detailed results for all those promoted are here. Note that the test data for the cowland problem was strengthened a bit prior to final grading.

Final Remarks
The 2018-2019 season is nearly finished! -- just the US Open contest to go. This contest went quite smoothly; there were no technical issues or issues with problem clarity. Score distributions all look in line with expectations and historical trends. Perhaps the hardest division this time around was the gold division, which had a slightly more genererous promotion cutoff.
For those not yet promoted, remember that the more practice you get, the better your algorithmic coding skills will become -- please keep at it! USACO contests are designed to challenge even the very best students, and it can take a good deal of hard work to excel at them. To help you fix any bugs in your code, you can now re-submit your solutions and get feedback from the judging server using "analysis mode".
A large number of people contribute towards the quality and success of USACO contests. Those who helped with this contest include Dhruv Rohatgi, Matt Fontaine, Ethan Guo, Matthew Fahrbach, Nick Wu, Charles Bailey, George Xing, Spencer Compton, Mark Gordon, and Avichal Goel. Thanks also to our translators and to Clemson CCIT for providing our contest infrastructure. Finally, we are grateful to the USACO sponsors for their generous support: D.E. Shaw, Jump Trading, TwoSigma, and Ansatz Capital.
We look forward to seeing everyone again for the US Open contest.
Happy coding!
