The nerds behind the buttons

We sacrificed 5 years of our lives (and our social lives) so that you can pass your theory within a week. You're welcome.

Why we built Theorio

Everyone can agree on at least one thing: Theory books are abnormally boring. Nothing sticks, and you learn things without being sure if you actually need to know them. That's what the whole book boils down to.


We don't believe in boring walls of text or day courses where you pay €150 to sit in a stuffy room with 60 people. We believe in the Duolingo method (but where you actually learn something). Short quizzes, knowing immediately what you did right or wrong, learning only what you need to know, and a bit addictive.


Our goal is crazy simple: To let you pass without falling over from boredom.
