Twelve areas to drill, each with its own exercises and games. The long explanations live in the grammar guides. This part is just practice.
You get a sentence with a gap: Ich gebe ___ Kind den Ball. Choose dem or den. All four cases show up this way, inside sentences you would actually say.
Der, die or das, one noun at a time. There is also a lookup dictionary with over a thousand nouns when you just need to check one.
Strong, weak and mixed endings. Ein neuer Tisch but der neue Tisch, and that difference is what you drill here.
Regular and irregular verbs across the tenses. There is a conjugator tool too, for when you only need the table for one verb.
Which preposition takes which case. Wechselpräpositionen are the awkward ones: in das or in dem, depending on whether you are moving.
Pronouns in every case, including the reflexive and relative ones. Mir or mich, ihm or ihn.
Mein, dein, sein, ihr, and the endings they pick up in each case. Meinem Bruder takes some getting used to.

Nominativ marks the subject and Akkusativ marks the direct object. Der Mann sees something; you see den Mann. Only masculine nouns change their article, which is why the other genders feel easy until Dativ turns up.
Nine prepositions that take either Akkusativ or Dativ depending on meaning. Movement takes Akkusativ, position takes Dativ: ich gehe in die Küche versus ich bin in der Küche.
No. The exam section drills the grammar those exams test, from A1 to C1, and finishes with a timed readiness check. It is not a mock exam, and we are not affiliated with Goethe, telc, or any other exam provider.
Flashcards, dialogues and stories play audio files we generate ahead of time, so the pronunciation stays consistent. Your device's own voice only steps in when a word has no file yet.
