About

Hello, my name is Colston! I'm a student from Northern California, and I love helping others learn. Tutoring is the best way to learn, after all. If you really understand a topic, you can break it down into simple terms and concepts.

Outside of academics, I play euphonium in both marching and concert band, which means I have an intermediate level of music theory knowledge. I also enjoy skiing and exploring intro-level coding, like Java and JS. Additionally, I'm a volunteer math tutor for my own school, and I'm starting up a Destination Imagination club. I'm always looking to challenge myself.

Everything Triangles

Starts Wed Feb 4, 2:00 AM

Triangles are three sided polygons with a lot of unique properties. From finding the distance between two points, to finding the area of any regular polygon, and even to trigonometry, triangles appear in a lot of places throughout mathematics.

Math for the March 2026 SAT

Thursdays 1:45 PM, Fridays 1:45 PM

Hi, my name is Colston K, and I'm really excited to help you prepare for the SAT! I've been a math tutor on Schoolhouse.world since January 2025, and I'm also a volunteer tutor for my high school. Nice to meet you!" This four-week tutoring series will help you prepare for your upcoming SAT in Math. By the end of the series, you will have completed multiple practice tests and worked through a number of problems from previous SATs, helping you build confidence for your upcoming exam. You’ll spend each session with me and a small group of other learners who are also working towards taking the SAT. Since it’s a small group, you can expect sessions to be very interactive as you work together towards improving your SAT skills as much as you can! Note: Cameras should be on so we can all get to know each other! If you have a specific reason why you can’t have your camera on, please notify me ahead of time.
