(CEMC Gauss Focus)
The Gauss 8 Contest is a multiple-choice mathematics competition for Grade 8 students, organized by the University of Waterloo’s Centre for Education in Mathematics and Computing (CEMC). It tests mathematical problem-solving and logical reasoning skills, with questions based on the Canadian Grade 7 and 8 math curricula. The contest has 25 multiple-choice questions divided into three sections, with difficulty increasing progressively. Students complete the contest within a set time and face challenges appropriate to different skill levels.
Instructor:

Binhang Zhu (Peter)
I am a graduate of the Medical Science and Computer Science programs at the University of Western Ontario. A dedicated community leader since Grade 7, I currently serve as a Supervisor for the Chinese Emotional Support Hotline at ECSSEN Career School. In this role, I lead, train, and mentor volunteers to ensure the delivery of compassionate, dependable emotional support to individuals in need. Through consistent guidance and role modeling, I have enhanced service quality and cultivated a supportive, empathetic environment that positively contributes to community well-being.
In addition to my volunteering in emotional support services and medical research, I serve as a Vice President responsible for teaching and coordinating physics and mathematics instruction. Through this leadership role, I have supported both individual student development and the broader educational growth of the community. This year, I plan to continue my Gauss 8 mathematics lessons, focusing on Questions 24 and 25 from the 2017 contest, as well as covering the 2016 and 2015 Gauss competitions. I welcome constructive feedback as I strive to continuously improve the quality and impact of my teaching.
