Online Tutoring · Based in Philadelphia
Smart students get stuck.
Let's figure out why.
Some students understand the material but lose points on the test. Others study for hours and still feel stuck. And some can't get organized enough to begin. Those are different problems, and they need different fixes.
I'm Andrés — Cornell grad, former NYC public-school math teacher, twenty years of teaching. I figure out what's getting in the way, then build a plan around it.
One-on-one online tutoring for SAT, GMAT, math, economics, writing and executive functioning, middle school through grad school.

I don't believe in more work for the sake of more work.
I want to know why something isn't clicking. Maybe a student keeps making the same algebra mistake because they never really understood fractions. Maybe they know the SAT material but take the slowest possible route through every question. Maybe there's a good college essay buried under five paragraphs of what they think an admissions officer wants to hear.
Once we find the real problem, we can actually work on it.
What I Teach
From math to test prep to getting organized — I've tutored it all.
SAT Prep
Stop practicing everything. Start working on what costs you points. We find your highest-priority skills, work on test strategy, and practice in Homework Forge, the adaptive SAT app I built for my students.
Math
Pre-algebra through calculus. We find the step that stopped making sense, repair it, and build from there.
Economics
AP Micro and intro college microeconomics. Learn to read the graphs and solve problems you haven't seen before, not just memorize definitions.
Executive Functioning
For students who struggle to start, keep track of assignments, manage deadlines, or follow through. We build systems they'll actually use.
College Essays
Find what you want to say, then write an essay that sounds like you, not like an admissions brochure.
GMAT
Focused prep for Quant, Verbal and Data Insights, built around your weak spots and your work schedule.
Vibe Coding
Build real projects with AI tools and just enough code. No CS degree needed — just curiosity.
SAT Score Predictor
Free. Takes two minutes. Tells you where your current plan lands.
Free SAT Practice
Try 10 SAT questions, no sign-up. It picks what you need next.
What working together looks like
We talk
The first conversation is free. Tell me what you're working toward, where you're stuck, and what you've tried. I'll tell you how I'd approach it.
We get to work
One-on-one sessions built around what you actually need. We work through problems and talk through your reasoning, so you understand what you're doing.
You practice, we adjust
Between sessions you practice in Homework Forge, the app I built, on exactly what you need next. When something isn't working, we change the plan.
The goal isn't to need tutoring forever. It's to become a stronger, more independent student.
