A frictionless, step-by-step math platform designed by an MIT grad and Math Olympian with the help of AI. Your child starts where they’re comfortable and builds real mastery through thinking, not guessing.
MJ brings together the most effective teaching methods from around the world. We combine structured discipline with deep conceptual learning to build a foundation that lasts.
Inspired by Japanese learning systems, we focus on daily consistency and small steps. Students master one skill before moving to the next, building fluency without feeling overwhelmed.
Drawing from Singapore Math, we move beyond rote memorization. We use visual models (like bar modeling) to ensure students understand the why behind the numbers, not just the how.
We use AI in many aspects of our curriculum, from analyzing mistake patterns to generating targeted examples and hints, ensuring your child gets the precise guidance needed to solve problems independently.
I started MJ because I saw talented students struggling not because they weren't smart, but because they lacked the right system. Drawing from my experience as an IMO Representative and MIT graduate, I built MJ to banish guesswork and build real mathematical confidence.
"I was looking for something to complement the international curriculum, specifically the rigorous practice that is often missing. MJ is perfect because the system is available in English, matching the language he learns at school."
"I really like MJ. The children are getting better in solving problems because they practice a lot. However, parents still need to supervise children doing the exercises; otherwise, they might not finish the homework in time."
"Math at school is quite advanced, but MJ helps me keep up. The system does not let me guess the answer — I have to actually solve it to type in. The examples and hints are like having a teacher teaching me when I get stuck on difficult new problems."
"There are numerous math exercises in MJ, and I initially made several mistakes. Nevertheless, through repeated practice, I have honed my skills to the point where I can now successfully tackle them."
"We used to struggle to get our daughter to practice math. With MJ, the system feels rewarding, almost like a game. She opens the app herself to keep her daily streak. The best part is the report sent to parents—I know exactly which topics she has mastered and where she still needs help."
"The competition is high, so accuracy is key. MJ Instant Feedback helps me fix my mistakes immediately, so I don't practice the wrong way. I feel much more confident tackling complex problems now, and my exam scores have consistently improved."
"After learning about fractions on MJ, my child happily grasped the concept. The other day, he took the Gifted exam at school, excelling, likely due to extensive practices with thousands of problems using MJ system."
"Since enrolling in MJ course, I've noticed significant improvements in my math skills. Tutors here employ effective teaching methods, making the learning less stressful. Various helpful shortcut formulas has contributed to my success. I currently rank at the top of my class."
"As a mother, I like the convenience of online learning. Despite residing in a different province, we can access star tutor from Bangkok. MJ system is very user-friendly. Both my children independently manage their homework. In particular, one child got a perfect score in the recent math exam."
"I like MJ system because it provides instant checking and allows for immediate corrections without the need for a teacher to review. It's like playing a game. I do MJ on iPad, making it possible to complete assignments anywhere, even at the dentist's office."
