What it is
Inburgering A2 exam practice for busy, English-speaking expats in the Netherlands. Questions stay in Dutch, on a screen that looks like the real exam, while explanations and feedback are in English.

What ships
- Practice for all five exam parts: reading, listening, speaking, writing and Knowledge of Dutch Society.
- Modules built around one everyday situation, moving from vocabulary and grammar to an exam-format question and its correction.
- Questions anyone can try without an account; the first five practices in each part are free, and unlimited practice is a monthly plan.
- An interface in English, Dutch, Spanish and Portuguese.
