How do I know I have finished an Anki deck?

When should I consider a premade anki deck to be "finished" in order to move on from it? Should I shoot for 100% mature cards?

1. Open the Anki Browser (shortcut: b).
2. From the left sidebar select the deck you want to check.
3. Add is:new to the search query.

If there are no new cards left, you're done.

Aiming at 100% mature cards is unreasonable. When you fail a mature card, it might revert to a young card.

When you start a new deck, continue reviewing your previous decks. Forgetting is inevitable, so you must review all your decks consistently to retain the material. Alternatively, you could keep all your cards in a single deck or create subdecks within a main deck.
