With Flash you can easily create index cards. You can create your index cards individually in the app or import them from an existing document.
Then you can practice the cards.
Index cards that you do not master well enough or forgot again can be saved in an extra watchlist. Keep track of the cards you have lernen & save time by only studying those you haven't mastered.
Each topic can be divided into several chapters.
The chapters can be learned individually or together.
Furthermore there is the possibility to add questions to learning lists and to repeat them separately.
