Xiangtao (Eddy) Liu
Master of Quantitative Finance at the University of Waterloo
Bachelor of Mathematics with Honours in Pure Mathematics at the University of Waterloo
Eddy began coaching mathematics competitions at Toronto Math Circles in 2013. Under his guidance, students have achieved remarkable success in prestigious competitions such as the American Regions Mathematics League (ARML) and the Harvard-MIT Mathematics Tournament (HMMT). He currently serves as the head coach of Ontario’s ARML and HMMT teams.
Eddy has also played a pivotal role in training most of Canada’s past European Girls’ Mathematical Olympiad (EGMO) team members and several International Mathematical Olympiad (IMO) team members. Several of his students have attended top universities, including MIT and Harvard. See the Achievements section for a list of past top students.
Over the years, Eddy has actively contributed to various competition problem committees, helping design, refine, and grade problems for regional, national, and international contests.
In his spare time, Eddy supports the mathematics community as a volunteer consultant for student-run organizations such as the Ontario Competitive Mathematics Committee and Tops Online Judge, where he provides guidance to students interested in competitive mathematics. He also regularly gives free workshops at high school math clubs, math camps, and hackathons.
Outside of math, Eddy is an avid skier, runner, and hiker.
Online Classes
All our classes are conducted online. While onsite classes can be more fun and engaging, they often come with drawbacks like wasted travel time and potential distractions from disruptive peers, which can affect the pace of the class. Online classes eliminate these issues, allowing both teachers and students to focus without disruptions. Moreover, online classes can cover more material than onsite sessions.
Weekly Take-Home Quizzes
Research shows that weekly quizzes are more effective for learning compared to large exams. Therefore, most of our courses include a weekly take-home quiz. This approach maximizes learning while preventing valuable class time from being spent on lengthy tests.
Homework Support Class
Although we post solutions for all homework assignments, many courses also offer a free weekly homework support class. In this class, teachers review the homework and quiz material. Even if you’ve mastered the problems, we highly recommend attending these sessions, as teachers often offer better, more efficient solutions.
Recordings
Class recordings are made available to students at the end of each week. This feature allows students to catch up on missed lessons or revisit difficult concepts at their convenience.
Community and Student Events
Our vibrant Discord community connects students with classmates, teachers, and graders for ongoing discussions about homework and course content. We also host regular educational and fun events, such as contests and advent calendars, to keep students engaged.
Hint System
Our website features an integrated homework hint system, providing support for challenging problems whenever you need it.
