About Harris

Bio

Hello! I’m Harris C, a junior at Columbia University studying Computer Science and Math/Physics. Over the years, I’ve learned that a lot of concepts only clicked for me after revisiting them from different angles, asking “why” instead of memorizing steps, and talking things through one-on-one. Thus, during lessons, I focus on clear explanations, active problem-solving, and making sure students actually feel confident with the material, not just prepared for the next test.

Hello! I’m Harris C, a junior at Columbia University studying Computer Science and Math/Physics. Over the years, I’ve learned that a lot of concepts only clicked for me after revisiting them from different angles, asking “why” instead of memorizing steps, and talking things through one-on-one. Thus, during lessons, I focus on clear explanations, active problem-solving, and making sure students actually feel confident with the material, not just prepared for the next test.

I scored a perfect 36 on the ACT and a near-perfect 1570 on the SAT. At Mathnasium, where I spent a year tutoring students from Algebra 1 to Calculus along with SAT prep, I developed a teaching method that combines conceptual understanding with practical problem-solving skills. Furthermore, I achieved scores of 5 on all AP Physics exams and qualified for the physics olympiad. Please feel free to reach out with any questions or to schedule a session!
