Round 1 Problems, Solutions, and Results are Available!

Thank you for joining us in a new season, new and returning participants alike! This round was certainly a learning experience for us. Due to an unexpectedly high level of participation, our grading system was unable to handle the load for the first time in four years! Instead, the contest was run effectively in “offline submission mode”. The system has been improved, so we are hoping for the best in round 2. We appreciate your bearing with us through the technical difficulties!

In spite of hardships with grading, perfect scores were attained in all of the divisions. Returning champion Zixiang Zhou of London Central Secondary School came out on top in the senior division. A fantastic comeback – keep up the good work!

The senior division prizewinners for this round are: 

  1. Zixiang Zhou of London Central Secondary School ($100)

  2. Andrew Qi Tang of Erindale Secondary School ($50)

  3. Royi Luo of Richmond Hill High School ($25)

  4. Sunny Lan of Richmond Hill High School ($25)

  5. Alex Tianyi Xu of White Oaks Secondary School ($25)
