## What makes Brilliant different?

“A significantly greater number of students fail science, engineering and math courses that are taught lecture-style than fail in classes incorporating so-called active learning that expects them to participate in discussions and problem-solving beyond what they've memorized.”
— “Enough with the lecturing”, National Science Foundation

Brilliant is built by educators, students, and practicing professionals who share an ideal for a better way to learn. When building material for our members, we take a look at the existing resources through the lens of our 10 principles, and our experience as teachers and students to produce a unique approach to the subject.

## Don't just take our word for it...

4.5 million members have used Brilliant to learn faster and overcome conceptual roadblocks. The press has noticed, too. Read more testimonials
