Online Tutoring for High School & College Students

Online Math & Computer Science Tutoring

Math finally makes sense with one-on-one online tutoring in calculus, linear algebra, Python, computer science, physics, data science, and SAT math.

This week I'm helping students with: Calc I–III finals, AP Calc AB/BC review, linear algebra exams, Python homework, machine learning intuition, and SAT math prep.

Hi, I'm Alexander — Your Guide to Actually Understanding Math & CS

Here's something I've learned after six years of tutoring at Texas A&M and working independently: every student who walks in thinking "I'm just not a math person" walks out realizing they were wrong. The issue was never ability — it was approach.

My job isn't just to show you the correct answer. It's to figure out exactly where you're stuck, then guide you toward the solution in a way that makes you say "Oh, that actually makes sense." I won't just solve problems for you. I'll ask the right questions so you connect the dots yourself — because that's how real learning happens.

When you understand the "why" behind a concept (not just the "how"), everything clicks. Homework gets easier. Tests feel less scary. And that anxiety you've been carrying? It starts to fade.

How I Help You Succeed

Four principles that turn struggling students into confident ones

01

Meet You Where You Are

Before we dive into new material, I figure out exactly where your understanding breaks down. No assumptions, no judgment — just honest assessment so we can build from solid ground.

02

Guide, Don't Just Tell

I won't hand you answers. Instead, I'll ask questions that help you discover solutions yourself. This approach builds problem-solving skills you'll use long after our sessions end.

03

Build Real Understanding

Memorizing formulas only gets you so far. I focus on the "why" behind every concept, so you can adapt your knowledge to any problem — not just the ones you've seen before.

04

Grow Your Confidence

Nothing beats the feeling of solving a problem you thought was impossible. Every small win builds momentum, transforming math anxiety into genuine capability.

Subjects & Specialties

From foundational algebra to advanced machine learning — I've got you covered

Mathematics

Algebra 1 & 2 Geometry Trigonometry Precalculus Calculus Linear Algebra Differential Equations Discrete Math Real Analysis Probability Statistics SAT Math GED Math Business Math
Whether you're struggling with high school algebra or pushing through college-level analysis, I tailor every session to your current level and goals.

Computer Science & Programming

From your first "Hello World" to complex algorithms — I break down programming concepts in ways that actually stick.

Data Science & AI

My specialty. I've built ML systems professionally and can help you understand everything from basic concepts to neural network architectures.

Physics

Physics is just math with a story. I help you see the connections between equations and the physical world they describe.

Bring Me What You're Stuck On — I'll Take It From There

You don't need a polished question or a study plan. Bring the real thing and we'll build the plan together.

A specific homework problem

Screenshot it, paste it, or share your screen. We start at the moment the problem stopped making sense and rebuild from there.

An exam in a few days

Send me your topic list or a past exam. We'll do a targeted prep plan with high-yield practice, not a chapter-by-chapter slog.

"I just don't get the concept"

If integration by parts, eigenvalues, or recursion still feels like magic, we'll build the intuition first — then the mechanics fall into place.

A coding bug that won't budge

Stuck on a Python error, a recursion that doesn't terminate, or a neural network that won't learn? We debug it together and you walk away knowing why it broke.

Test prep — SAT, GED, AP

We diagnose where points are leaking — careless mistakes, timing, or content gaps — then drill exactly those, not the whole test.

Just a vague "I'm lost"

That's actually the most common starting point. The first 30 minutes are free — bring your textbook, your last test, or your syllabus and we'll figure out where to start.

A 60-Second Sample

How I'd Walk You Through a Related-Rates Problem

This is the kind of step-by-step thinking we'd use in a session — not "here's the answer," but "here's how to see the problem."

Problem: A ladder 10 ft long leans against a wall. The bottom slides away at 2 ft/s. How fast is the top sliding down when the bottom is 6 ft from the wall?
  1. Draw it. Right triangle. Label the bottom as x, the top as y. The ladder length (10) stays constant.
  2. Write what you know in math. x² + y² = 100. We know dx/dt = 2. We want dy/dt at the instant x = 6.
  3. Differentiate both sides with respect to t. That gives 2x · dx/dt + 2y · dy/dt = 0. This is the step that always feels weird — but it's just the chain rule talking.
  4. Find the missing piece. When x = 6, the Pythagorean theorem gives y = 8. Now plug everything in.
  5. Solve. 2(6)(2) + 2(8)(dy/dt) = 0dy/dt = -1.5 ft/s. The negative sign is the answer telling you the top is going down.
The real lesson: Related rates always follow this pattern — relate the variables, differentiate, plug in last. Once you see the shape, the rest is algebra. That's the kind of pattern recognition we build session by session.

What Students Say

Real results from real students who thought they couldn't do it

"Alexander is a great tutor! He was patient with me when I didn't understand something, and he broke it all down so I could get it. He was instrumental in helping me salvage my C programming course, which I ended up passing with a decent grade, in just four lessons. I only wish I'd found him sooner."

E

Ethan

Brooklyn, NY • C Programming

"Rather than focusing only on syntax or tools, Alexander emphasized understanding the why behind the code — which greatly improved my grasp of key concepts. What truly set him apart was his patience and ability to adapt explanations to my level. I would highly recommend him to anyone looking to build strong foundations in Python, data analytics, and algorithms."
