Online Tutoring · Based in Philadelphia
Smart Kid.
Bad Scores.
Sound Familiar?
Your kid gets it in class but freezes on the test. Or they're sharp but disorganized. Or they just need someone in their corner who actually knows the material. I'm Andrés — Cornell grad, two master's degrees, twenty years of teaching. I'll figure out what's going on and fix it.
SAT prep, math, economics, writing, executive functioning — middle school through post-grad. All sessions online.
What I Teach
From math to test prep to getting organized — I've tutored it all.
SAT Prep
I've helped tons of students raise their SAT scores by 100–300 points. We start with a diagnostic, build a plan, and work through it together.
Math
Pre-algebra through calculus. I focus on understanding the why, not just memorizing steps.
Economics
Micro, macro, AP Econ, and college-level. I make it click.
Executive Functioning
For students who struggle with managing their workload — often those with ADHD, learning differences, or just general difficulty staying organized.
College Essays
Your essay is your chance to show admissions officers who you are beyond grades and test scores. I've helped tons of students get accepted into top-tier colleges.
GMAT
Targeted GMAT prep, built around your schedule. I work at your speed and keep it humble, focused, and real.
Vibe Coding
Build real projects with AI tools and just enough code. No CS degree needed — just curiosity.
Free Tools
Score predictors, study timers, and practice resources — free for all students.
Here's How We Work
We Talk
We start with a free consultation. You tell me what's going on, I ask some questions, and we put together a plan. No commitment.
We Meet
Weekly sessions, one-on-one, focused on what you actually need. If something isn't working, we adjust.
You Practice
Between sessions, I'll give you targeted work to keep the momentum going. No busywork — just the stuff that moves the needle.
