My name is Jeffrey Liu, and I'm one of the teachers at PLAY Math. I am an 8th grader attending Hart Middle School in Pleasanton.  My math experience is up to Geometry and Algebra 2. I am also doing AMC 8/10 at the moment. Outside of math, I also enjoy painting. I am very competitive, and I want students to win. And by win I mean doing well on assessments (CogAt or placement) and learning all the material.
