Sprungbrett Deutsch
German practice for A2 learners. Exercises check answers right away, and guests can try it without an account.
Why
Learners preparing for A2 need short daily practice with instant feedback, not a pile of PDFs.

- Flashcards with spaced repetition and a writing area with model texts and self-assessment
How it is checked
