How are words selected for the Quiz?

Spaced Repetition

Wokabulary automatically applies a spaced repetition scheme on your words.

As you do quizzes, words get automatically sorted in difficulty levels. When you answer a word correctly in the quiz it rises to the next higher level. If you answer it wrong, it drops to a lower level.
The higher the level, the better you know a word and the less often you need to review it. So the time intervals after which a word is recommended to be quizzed again increase with the level.

Repetition pattern

Wokabulary recomends words for a quiz according to the following repetition pattern:

Unknown: After 1 day
Level 1: After 2 days
Level 2: After 5 days
Level 3: After 12 days
Level 4: After 4 weeks
Learned: After 9 weeks

Wokabulary automatically selects the words for the quiz which should be practiced at that moment.
Of course, you can always do a quiz on any other selection of words you like by using a custom filter. And you can always select more words than what is recommended.

Word selection

Wokabulary will select words in the following order:

1. All words from levels 1-4 that are recommended to be asked
2. If that is less than the number selected for the quiz:
   Recommended words from the unknown level with those that have recently been asked first
3. If that is less than the number selected for the quiz:
   Recommended Words from the learnt level
   
4. If that is less than the number selected for the quiz:
   Equally add not-yet-recommended words equally from all levels
