Nothing is due right now. Take a test — every question you get wrong is added here automatically.
How this works
Each card carries a stability (how long the memory lasts) and a difficulty. Rating a card updates both, and the next interval is the point where your recall probability falls to 90%.
Rating Again shortens stability sharply and returns the card later in this same session — not tomorrow.
Weights are the published FSRS-4.5 defaults. Once enough of your own reviews accumulate they can be refitted to you specifically.
