The order of difficulty of the problems as indicated by the scores, starting with the hardest, was 5,2,7,6,1,4,3.
As usual, several students failed to put their registration number on their solutions. Some of the solutions we could not assign to a student, in other cases we made a guess (so it is possible a students got points he/she never actually got). Also, some registration forms weren't filled out.
I'm grateful for help from Edgar Saenz, Steve Galinaitis, Sohei Yasuda, Jeffrey Truman and Leonardo Mihalcea.
I would like to thank all the schools who took part, and I hope you will all take part again next year. I also hope that many schools who did not take part this year will take part next year. Watch these WEB pages; even if you do not get an invitation, we will still be delighted for you to take part provided you fill in the registration forms before the closing date for entries.
The most likely date for the contest next year is Saturday, October 26 2019. Occasionally announcements about the competition will be posted in the Sci.Math newsgroup.
