Round 3 Problems, Solutions, and Results are Available!

Baring a few test data hiccups, the Woburn Challenge online round 3 was a refreshing start to the new year. We are proud to have so many new rising stars tackling the challenges we work so hard to craft.

After a nail-biting defeat in round 2, returning finals champion Zixiang Zhou of London Central Secondary School has made a comeback over Brian Chau of Woburn. Zixiang was the only competitor to solve the final senior problem, and did so only half-way into the contest! Meanwhile, Michael Huang of Bell High School topped out the intermediate division in 40 minutes flat. Keep up the great work!

The senior division prizewinners for this round are: 

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

  2. Brian Chau of Woburn Collegiate Institute ($50)

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

  4. Andrew Dong of Centennial College Vocational Institute ($25)

  5. Ava Pun of Marc Garneau Collegiate Institute ($25)

  6. Anish Mahto of Turner Fenton Secondary School ($25)
