completely learned?

Each time you finish learning a card in all the modes then the card will go to "Sleep" for a couple of days. Then it will "wake up" and needs to be learned again. The time a card sleeps is increased continuously. After a defined number of times the card will be "Completely learned".

With trainchinese you can define yourself, how many times you want to let a card sleep until it is completely learned. You also can define how many days a card should sleep. To configure this parameters please use the Settings button after logging into trainchinese.
