Hi! I’m Hongyu and I am currently studying for my Master of Education at OISE, University of Toronto. I’m also a certified teacher (OCT). I completed my Bachelor of Science and Bachelor of Education in Kamloops, BC, where I got my BC teaching certification before moving to Toronto.

I specialize in teaching math and physics for grades 9-12, and I’ve also taught Chemistry 11. Whether it’s Pre-Calculus, Advanced Functions, or Calculus, I love helping students tackle challenging concepts and build confidence.

I’m originally from China, so Mandarin is my first language, but I’m fluent in English too—so no worries about communication! Outside of teaching, I’m into photography, traveling, working out, and I’ve recently started learning video editing.

Looking forward to working with you and helping you reach your academic goals!
