About Kai


Bio

I'm Kai, an Applied Mathematics student at the University of California, Berkeley. I graduated from The Bay School of San Francisco with a 4.0 unweighted GPA and a 1530 on the digital SAT (780 Math, 750 Reading & Writing).

As a tutor, I specialize in helping students raise their SAT math scores by using official College Board materials and the Desmos graphing calculator, which is built into the digital SAT. I also developed desbros.org, a resource designed to teach high school students how...

I'm Kai, an Applied Mathematics student at the University of California, Berkeley. I graduated from The Bay School of San Francisco with a 4.0 unweighted GPA and a 1530 on the digital SAT (780 Math, 750 Reading & Writing).

As a tutor, I specialize in helping students raise their SAT math scores by using official College Board materials and the Desmos graphing calculator, which is built into the digital SAT. I also developed desbros.org, a resource designed to teach high school students how to use Desmos efficiently and intuitively—a skill that is key to scoring well on a test that rewards speed and accuracy.

Currently, I’m working for Crackd (crackd.it), a leading SAT prep platform, where I contribute SAT math curriculum, developing structured, self-paced lessons and video tutorials that break each major question type into consistent, repeatable strategies.

My approach focuses on identifying the patterns behind SAT questions and helping students apply consistent, repeatable strategies. I've built an interactive, self-paced SAT math course that covers major question types, walks through detailed problem-solving techniques, and features integrated practice questions to reinforce understanding.

At UC Berkeley, I have completed Calculus II, Calculus III, linear algebra, and differential equations. My background also includes advanced high school coursework in calculus, linear algebra, quantum mechanics, and physics. In these courses, I regularly assisted my classmates by explaining difficult concepts and working through challenging problems together. I have experience tutoring middle and high school students across a wide range of abilities and learning styles.

My goal is to create a supportive, collaborative environment where students build both confidence and independence, inspiring curiosity in how they approach mathematics and giving them the tools to tackle new problems on their own.

I tutor students specifically for the new digital SAT Math section, focusing on adaptive test strategies and advanced Desmos graphing calculator techniques. I teach students how to streamline problem-solving, recognize common question patterns, and manage time effectively to maximize their score. I scored a 1530 on the digital SAT (780 Math, 750 Reading & Writing) and am up to date on the exam’s structure, tools, and strategies—including many insights that most tutors are not yet familiar with.
