About Alexander

Bio

Hello everyone! I am Alexander, a freshly experienced mathematics instructor with a passion for helping students unlock their full potential. I hold a Sc.B. in Applied Mathematics - Biology from Brown University. My tutoring journey began at the Brown Math Resource Center, providing academic support in Calculus and Linear Algebra to my undergraduate peers. Since graduating, I have dedicated myself to teaching students across a wide range of ages and skill levels.

I have extensive...

I have extensive experience in both one-on-one and small-group settings. At Mathnasium, I led instruction for students from kindergarten through 12th grade. Currently, at True Education, I teach K-12 students in focused, two-hour sessions with a 3:1 student-to-teacher ratio. My primary focus is helping high schoolers master SAT Math, ACT Math and Science, and AP STEM courses. Additionally, I serve as a Mathematics Adjunct Instructor at Lanier Technical College, instructing adult learners in College Algebra. This diverse background has taught me how to break down complex concepts into manageable pieces for any age group.

My tutoring philosophy centers on cultivating academic independence. To keep sessions accessible and straightforward, I utilize free, high-quality open-source textbooks from OpenStax—meaning you only ever need to bring a notebook, your schoolwork, and a readiness to learn! I focus on identifying knowledge gaps and using test-review questions to build problem-solving confidence. Whether we are tackling test-taking strategies or college-level applications, I strive to create a supportive environment. As a native Spanish speaker, I am also happy to offer bilingual support. Let's work together to achieve your academic goals!
