Every student is a sum of their own potential.
Personalized 1-on-1 math tutoring for K-12 students, from elementary math through AP Calculus. Your kid gets one dedicated tutor, and you get progress you can see week to week.
Simple from day one.
Book a free first session, meet the tutor, and decide from there. You never sign a long-term contract, and if it isn't a fit you've lost nothing but an hour.
Book a Free Session
The first session costs nothing and doesn't commit you to anything. We meet your student and figure out where the gaps are and what they're aiming for.
Get Matched to a Tutor
We match your student with a tutor who fits their subject, grade level, and way of learning, rather than whoever happens to have an open slot.
Choose Your Plan
Pick a session package that fits your schedule. Prices are listed right on this page, and we'll help you size it after the free session.
Track Progress Together
Your tutor logs notes and progress after every session, so you can see how things are going without having to ask.

SAT prep uses the same session packages and pricing as regular tutoring. We'll recommend the right pace at your free consultation.
Why our SAT prep is different.
Most prep programs teach every student the same material. We don't. We find your student's specific weak spots and attack those first.
- Week 1: a full diagnostic, so we know where to start
- Weeks 2 to 6: focused work on the gaps the diagnostic found
- Week 7: a full practice test to measure the improvement
- Week 8: test-day strategy and final review
Parents trust SumOf1.
Real families, real progress.
"My daughter was struggling in Algebra II and Trigonometry — not because she couldn't do the work, but because the way it was being taught just wasn't clicking for her. Since working with her tutor, everything has started to make sense. She's gained back her confidence in math. Patient, effective, communicative, reliable. 10/10."
"Both of my sons worked with SumOf1 throughout the school year and had an outstanding experience — our older son has continued with SAT math prep this summer. What really sets them apart is making sure students truly understand each concept before moving on. Patient, encouraging, incredibly knowledgeable tutors. We couldn't be happier."
"I have struggled with math all my life — especially SAT Math, Algebra, Geometry, and Calculus. After using SumOf1, everything finally started to click! The tutors are incredibly knowledgeable, curating a unique experience based on each student's needs. I would highly recommend to any high schooler in need of a math tutor!"

Frequently asked questions.
Everything parents usually want to know before booking.
Is the first session really free?
Yes. You don't pay anything or enter a card. We use the session to meet your student and figure out where they need help, and afterward you decide whether to continue.
How do the sessions work?
Sessions run on Zoom with a shared digital whiteboard, so your student and tutor talk and work through problems together in real time. It's about as close to in-person tutoring as online gets. Your student keeps the same tutor from week to week, and sessions are scheduled around your family's calendar. After each one, the tutor logs notes and progress you can review.
What subjects do you cover?
Math for K-12: elementary and middle school math, Algebra I & II, Geometry, Pre-Calculus, AP Calculus, and SAT Math prep.
How much does it cost?
Packages come in 4, 8, or 12 sessions a month. Every session is 60 minutes and 1-on-1, and the same packages cover regular tutoring and SAT prep. Extra sessions are charged at your package's per-session rate, and your first session is free before you buy anything. Get in touch for current pricing.
What if the tutor isn't the right fit?
Tell us and we'll rematch your student with a different tutor. It happens sometimes, and it's a quick fix.
