The big grammar check

One last pass over the eight traps from Units 1–9 — one per sub-lesson, with fresh sentences:
- endings & sein/haben
- ein/einen
- the cases: der/den/dem
- kein/nicht
- separable verbs
- Perfekt: haben/sein
- du/Sie
- verb position
Still shaky on one? That’s your signal to revisit its unit before the mock exam.
Tip
These eight topics cover common A1 grammar difficulties. Use your mistakes to choose what to practise next.
