Mathematics tutoring targeted towards middle/ high schoolers

To first lightly introduce my academic background, I am a first-year undergraduate student at Imperial College London, attending an American high school in Japan.

Next, to explain what I will provide. Mathematics is not a memorization game, meaning that to gain mastery, you must understand the theorems or formulas and then practice them in different contexts. Therefore, I hope to present and teach you mathematics with reason and repetition. I have taught other students in small groups during high school and in my final year of high school, I was an assistant teacher for one of my math instructor's calculus classes. I can particularly help with geometry, algebra, calculus, and some introductory competition-style mathematics. The length of a lesson can be negotiated, and my target audience would be middle schoolers or high schoolers.
