Real Measurable Improvements You Can See (Before → After)
Thousands of parents have watched their children become confident and successful with Thinkster.
From danger zone to 80% above peers.
My daughter went from 'bombing math' and being in "danger zone" to showing growth that was 80% above her state peers after using Thinkster.
A second grader performing at a fifth-grade level.
It's amazing what a year of Thinkster can do! Her teacher told me it's the first time she saw any of her students score higher than a fifth grader! We are doing something right!
Thinkster Alyssa, a second grader actually showed performance at the 5th grade level on the STAR Math Assessment, just a year after she started working with her Thinkster Math tutor!
485 to 547 in under a year.
Thinkster Math did it in 1 year what Kumon could not do in 3 years!
From falling behind to the highest NAPLAN band.
Before starting Thinkster, Kiara was falling behind in Math, but these days she tackles complex word problems and has built strong calculation skills which have led her to achieve the highest band in the Australian Naplan National Test.
Kiara and her sister used to study math with Kumon in Australia before joining Thinkster. As two of our first Thinksters 'down under,' their math performance was outstanding—worthy of rock-star status! With Thinkster, they not only saw remarkable improvement but also truly loves math!
Off-the-charts NAPLAN performance.
Literally, Off The Charts Performance!!
Camille's performance in the national NAPLAN test was literally off the charts! Camille's parents chose Thinkster over Kumon for learning mathematics several years back because of the convenience of not having to travel to a learning center. Her parents shared, "Camille's got a full extracurricular schedule and we didn't want to drive her to yet another place, and we didn't want to grade her worksheets. She is also able to do Thinkster easily while we travel."
97th-99th percentile within a year.
Thinkster Math helped Suprav in building more confidence in math by identifying his strong and weak areas and working on them gradually to advance Suprav beyond his grade level which helped him achieve top scores no only in his class but also in his MAP tests
Suprav scored in the 97th-99th percentile on the North Carolina MAP test within a year after starting to study math with his Thinkster Math Tutor.
93% on MAP, with 20%+ growth.
Thinkster student Georgia's score of 93% on the International MAP Math test. During her two years with Thinkster, Georgia's math performance improved significantly, with her MAP results increasing by over 20%.
Nearly two years ahead of grade level.
Literally, Off The Charts Performance!!
Kaydee tackled math nearly two years ahead of her primary (elementary school) grade level. After switching from Kumon to Thinkster, she thrived and continued to make incredible progress. Solving different types of math problems became a breeze!
From shaky foundations to one of the top scores on campus.
...Thanks to his tutor and Thinkster, Soham has scored 86% in his state level and one of the highest in his campus...
Soham performed at the 'Master's Grade Level' on the Texas Assessment math standardized test! His strong foundation in math and working with his a math tutor for one to one support truly helped drive incredible results!
Top SBAC performance and national recognition.
Carys is a hard worker and takes school very seriously. She strives to be the best in everything she does. Carys was the only 4th grade girl in her school to obtain National Honorable Mention for the Noetic Learning Math Contest. We are very proud of her!
When in elementary school, Carys (from Connecticut) received the highest score possible on the SBAC. According to SBAC, students performing at this standard demonstrate advanced progress towards master of mathematics knowledge and skills.

If this feels familiar… you're not alone.. and this is not your child's fault.
You've noticed the signs. Maybe your child is visibly frustrated with homework, or maybe they're acing tests but still feel unchallenged. Whether it's slipping confidence or untapped potential, there's that parental instinct telling you they deserve more — more support, more growth, more joy in learning.
It's not because they can't do the math. It's not because the kid isn't trying. It's because the system was never built for your specific child.
School teaches 30 kids the same way. Other tutoring companies hand every child the same packet or drop six kids in a room with one rotating instructor. None of them can see where your child's logic actually breaks down.
So the gaps widen. Your child feels frustrated, let down, or not stretched to their potential. Slowly they start to feel that maybe they're “just not a math person” — and lose their sense of pride.
Does any of this sound like you?
Your child avoids homework — not because they can't do it, but because they hate it.
You hear “I'm just not a math person,” and worry they've started believing it.
They get good grades, but breeze through assignments without feeling stretched.
You've tried helping — even hired tutors — but something's still not clicking.
You're not sure if they need catch-up, challenge, or just the right kind of support.
You don't have the time, the right approach, or the patience for endless after-school worksheet drills.
If you checked even 2 of these — keep reading. We've helped 150,000+ families with the exact same experience.
I knew my daughter was capable of more — she was coasting. Thinkster gave her structure, stretch goals, and a sense of pride in her own progress.

The Short Truth
“Is Thinkster for kids who are behind, or kids who are ahead?” It's the wrong question.
A child who's behind and a child who's racing ahead have the exact same need: someone who actually understands how their mind works with math, and builds the next step from there. Behind, on pace, or ahead — the Method meets them where they are.
And that's exactly what The Thinkster Method™ does.
The Thinkster Method™
What is the Thinkster Method?
Every tutoring program — worksheets, apps, even most human tutors — grades what your child got right or wrong. The Thinkster Method™ reads why. It builds a real model of how your specific child thinks through a math problem: what representations land, where the reasoning actually breaks, what's a slip versus what's a misunderstanding.
That model is what makes everything else possible — the right next problem, the right explanation, the right pace.
How do we deliver it?
Through the Confidence Accelerator System — patented AI, a dedicated human tutor, and a real-time map of your child's thinking, working together.
Reads your child's thinking.Maps the mind.Fixes the why.

How the System Actually Works
Two kids. Same wrong answer. Completely different underlying problems.
Most programs see the wrong answer and assign more practice. Thinkster's PrediQt-AI™ Engine reads how your child got it wrong — not just that they got it wrong.
A procedural error means your child knew what to do but slipped on the calculation. Fix it with practice. A cognitive error means your child has the wrong mental model entirely. Fix it with a different explanation.
Same wrong answer. Two completely different responses. Most programs can't tell. Ours can.
Math isn't a list of topics.
It's an interconnected web.
Your child is stuck on fractions. But the real problem isn't fractions. It started six months ago — with division.
Division builds into fractions. Fractions feed into ratios. Ratios are foundational to algebra. When one thread breaks, everything built on it starts to unravel — silently, invisibly. You keep working on fractions. The gap keeps moving.
Thinkster builds a map of every concept and how it connects to every other. When your child's AI coach detects a gap, it traces the dependency chain backwards, identifies the root, and rebuilds from there.
Your child stops failing at fractions — not because they drilled fractions, but because the thing underneath finally became solid.
The reason some children love learning and others hate it: flow.
There's a state where learning feels effortless. Where time disappears. Where a child doesn't want to stop. It's called flow. It's not random. It's engineered.
Flow happens only when challenge and capability are matched. Too easy: boredom. Too hard: shutdown. Either way, your child learns nothing.
Most programs guess where that match point is. Most of the time, they guess wrong. Thinkster measures three real-time signals — learning velocity, engagement score, and struggle indicators — and adjusts the difficulty at the problem level, not the lesson level.
Children who learn in their flow zone develop something programs can't teach directly: the belief that they are capable learners.

A quick note from me (and why I built this)
Hi, I'm Raj Valli. I'm a dad first—and I've always been a 'systems' person. I'm a certified Six Sigma Black Belt, which basically means I obsess over making progress predictable instead of leaving it to chance. For 20+ years I've built 'no-guesswork' systems for performance—first in business, then for my own kids' learning.
My approach helped all three of my daughters reach big goals, including Ivy League admissions—but Thinkster isn't about Ivy League. It's about helping a child build real math mastery and confidence early, so doors stay open—whatever path they choose.
I built Thinkster because I couldn't find a program that consistently did that: a system that gives the right next step, fast feedback from a real tutor, and progress you and your child can actually see - so confidence becomes automatic.
Frequently Asked Questions
Here are the most common questions parents ask about Thinkster.
