Personalized Learning Plan
We make sure you're always given the right lessons at the right time, so you can maximize learning and minimize frustration.
Start with a diagnostic test to find your Knowledge Frontier.
Then move forward at your own pace, and never get stuck.

Efficient, Effective Learning
Complete each lesson in 20 minutes or less of focused effort.
Experience tons of animations and visualizations that make complex concepts easy to understand.
Get instant feedback on your answers so you can quickly upgrade your understanding instead of repeating mistakes.

Adaptive review
Save time and maximize long-term retention by only reviewing content when it's most needed.
We enhance the traditional spaced repetition system by using the knowledge graph - when you demonstrate mastery of an advanced concept, we know that the basic concepts used are also mastered.

Hear from some of our users:

"What I really liked about the platform is the pacing and the adaptability of it... Keep it up for a few weeks and before you know it you're doing real full fledged quantum computation that is directly used in things like Deutsch's algorithm. It's incredibly approachable even if you only have some basic college level math under your belt."

"I had some previous exposure to quantum computing, thanks to an IBM online tutorial and their cloud-accessible quantum computers. I also recently tried to participate in a quantum hackathon, but the open issues I investigated were way over my head. Now after taking the course from Lemnisket I'm ready to take another swing at it."

"This course wasn't just another online program. What they're building in the quantum education space is already making a real impact. It was so encouraging to engage with material that was accessible without compromising depth. A huge thanks to Lemnisket for helping spark a further interest in Quantum Computing!"
