ABiLearner

Flashcard app built for the Abitur. Decks are structured from the Kerncurriculum per subject (Biologie, Sport, Geschichte, Englisch – five active), and the spaced-repetition schedule is anchored to the actual exam dates you enter.

Standard flashcard tools optimize retention over an open horizon; the Abitur has a deadline. What matters is that a Biologie card resurfaces two weeks before Biologie, not some time in the summer after. The scheduler knows what's on which day and prices review time accordingly.

Weaknesses

First-time-wrong rate per topic feeds a Schwächen view – the topics where initial recall failed most get flagged, with pointers back to the reference videos that cover them. Not every card is equal; the ones that broke first are the ones to re-teach.
