Understand the rules,
not just the answers.

theorie.net is a free online platform for Germany's driver's-licence theory exam. The question pool is fixed and identical everywhere, so instead of another quiz wrapper, it's built around genuinely understanding each rule, with a guided study plan and an AI tutor. German, licence class B, free to learn.

The Why

Nearly half of learners fail. The exam isn't the problem.

In 2024, 45% of car-licence learners failed Germany's theory exam (TÜV-Verband). The catalogue of questions is official, fixed, and identical in every app, so the gap isn't the material. It's how people are taught to prepare for it.

Most apps optimise for memorising that pool: drill the questions, recognise the patterns, pass, forget. The interfaces feel a decade old, and the reasoning behind a rule is rarely part of the answer, so the moment a question is reworded or a real situation needs judgment, recognition falls apart.

theorie.net is built the other way around. Understand the rule and the answer follows. Every question carries a plain-language explanation of the why, an adaptive plan spends your time where it is weakest, and an AI tutor is there for the follow-up question, knowledge that still holds on the exam and on the actual road.

The Product

What you actually get.

A path from your first question to genuinely exam-ready, not an endless wall of flashcards.

Guided study plan
A plan that follows the official framework curriculum and adapts to what you've mastered and what still trips you up, so you always know what to learn next.
Explanations, not just answers
Every exam question comes with a clear, everyday-language explanation of the rule behind it. The point is to understand why, not to memorise which letter is correct.
Finn, the AI tutor
Stuck on something? Finn explains it in context and handles your follow-up questions, grounded in the official rules, so the help stays trustworthy.
Exam simulation & readiness
Practise under realistic exam conditions and get an honest read on whether you're ready, before you book the real appointment.
Concepts that connect
A glossary and themed "Theoriewelten" link related rules together, so you learn ideas in context instead of a thousand isolated questions.
Learn anywhere
A fast web app plus native iOS and Android apps, your plan and progress follow you from desk to phone.
How It Teaches

Built on how memory actually works.

The learning loop is grounded in cognitive science and carefully checked content, substance over gimmicks.

Learning science
·
Spaced repetition
Reviews come back just as you're about to forget them, so your time goes to what's slipping rather than what you already know cold.
·
Active recall
You retrieve the answer before you see it. That bit of effort is what moves a rule into long-term memory, recognising it isn't the same as knowing it.
·
Honest progress
Progress tracks real retention over time, not how many cards you've tapped through, so "ready" actually means ready.
Content & trust
·
Plain-language explanations
Every rule is rewritten in everyday German and checked for accuracy against the official sources, so what you learn is both clear and correct.
·
Grounded AI
Finn draws on the official rules and your own progress, and is built to stay within what it actually knows rather than improvise, help you can rely on.
