When learning to deck, all cards in the flashcard set are used and learned. If you answered the question right or wrong, the flash card will be marked as asked.
Once you have worked through all the flashcards in this stack, the entire stack of flashcards is shuffled and all the flashcards are queried again.
This goes on as long as you want to learn.
If you have chosen JA, the cards will be shuffled again after each pass. If you chose NO, the cards will be shuffled in the order you entered them.
With "Write answer" you can choose whether you want to say the answer orally, or whether you want to write down the answer. This function is best for learning vocabulary and words.
