In-Video Chat

You're not alone anymore. We've solved the problem of Zoom class being so boring that everyone secretly watches YouTube instead. The breakthrough was to put the chat on-screen, as a centerpiece to focus discussion and interaction. How? By moderating it. A feature that is not available in Zoom.

Improv Comedy

In each class, two live-streamers teach 40 students. Ideas flow in so many more ways, and elevate the excitement level of the class. This teaching style is our unique combination of performance techniques from improv comedy, combined with broad math expertise.

Powered by Po-Shen Loh

Live interaction? Or professional math insight and expertise, with crystal clear, polished, explanations? Who says you can't have both? Our live-streamers multiply the Prof. Loh effect by interspersing his short pre-recorded clips. With our technology, when they smoothly ask, “Prof. Loh, what do you think?”, it's just like he's in the room too.

Rolling Enrollment

We've cracked the code. Online courses are now more lively than in person. This lets us create class cohorts without geographical limitations. You don't have to squeeze your schedule around an 8pm class, or wait for the next season to enroll in a camp. Just share your times of availability, and our system will automatically search for schedules that match. We'll contact you as soon as we have one.

Actual Class Footage

Words can't describe how engaging and immersive this new experience is. See our techniques at work in this compilation video from a real hour of class led by two former MATHCOUNTS state champions. Video from students in the class has been removed for privacy.

Curriculum

Modules

The backbone of middle school math competitions. Efficiently covers important topics that are not part of standard school curriculum. Modules are available for a wide range of levels, from middle and elementary school students familiar with Pre-Algebra, to high school students who need to learn Combinatorics and Number Theory for high school math contests.

Hours per Module

Bite-sized classes. Structured around big questions that you get to think about, and discuss your ideas. Our streamers improvisationally lead students to discover how their ideas could contribute to a solution, before Prof. Loh's segment provides comprehensive coverage.

Carefully Designed Problems

Each module contains over 150 specially crafted problems, each of which teaches new concepts. Many are quite challenging. You'll discover abilities you never knew you had. Includes homeworks and practice tests.

Enroll Now

Each course costs $399, for 20 hours of instruction (~$20/hour).
