If you're having issues with the quiz feature, you may need to adjust the options you've selected. Some cards will be skipped if they can't be displayed in the selected quiz mode(s) or if the deck isn't large enough.
You can change your quiz options on the right side of the Study menu. It may require a little bit of experimentation to find the right options if you're struggling with a deck.
- Doesn't work with very short or very long cards
- Punctuation can make the questions difficult, at times
- May have obvious answers if the subject matter is diverse
- Requires 16 cards in the deck (4 questions with 4 answers each is the minimum)
