Round 2 Problems, Solutions, and Results are Available!

Round 2 ran as smoothly as Ethan Hunt himself! We were proud of the problem set, turnout, as well as the increased stability of the judge (all thanks to our admin Brian!). Now, here’s a Woburn Challenge fun fact for all of you out there: for the first time in over two years of online contests, there were no perfect scores in the senior division.

Top competitors were perplexed past the first subtask of problem S4’s mind-numbing traffic scenarios… until, crazily enough, with two minutes to spare, Brian Chau of Woburn managed to secure the subtask two for a dazzling finish. Returning champion Zixiang Zhou of London Central Secondary School has finally been dethroned! Will there be a comeback in rounds 3 and 4? Tune in in the new year to find out. Still, a nail-biting performance for all – keep up the great work!

The senior division prizewinners for this round are: 

  1. Brian Chau of Woburn Collegiate Institute ($100)

  2. Zixiang Zhou of London Central Secondary School ($50)

  3. Henning Jiang of Vincent Massey Secondary School ($25)

  4. David Tang of University of Toronto Schools ($25)

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

  6. Dan Bo Yang of Iroquois Ridge High School ($25)

  7. William Li of University of Toronto Schools ($25)

  8. Sharujan Sreekaran of Glenforest Secondary School ($25)

The intermediate division prizewinners for this round are:

  2. Jason Xiong of University of Toronto Schools ($25)

  3. Michael Huang of Bell High School ($25)

Finally, we would like to applaud a job well done to the top Junior division finishers: Moses Xu of Appleby College, Eric Wang and Leo Tong of Glenforest Secondary School, and Allen Tao of Colonel By Secondary School.

Congratulations! These prizes will be distributed as Visa gift cards during the on-site finals in May to which all of the above winners are invited (more details to come later). Do not fret if you may not be able to make the final round in person – we will mail your prize to you afterwards.

Remember that we will have many prizes in the remaining rounds of the year, so keep on practicing! Problems and solutions for this round are now posted at: woburnchallenge.com/past-contests. Once again, we thank all of you who participated, as well as teachers for sharing this with your students.

Last but not least, happy holidays from the Woburn Challenge Team!
