Quizlet automatically saves your progress when creating a new study set.
The next time you click on Create Set, you'll see this message.
Either continue working on the flashcard set and make sure to click "Create Set" at the bottom of the page. Or if you want to discard the flashcard set, click the "discard it" button and it will be permanently removed.
NOTE: Auto-Save only works on New sets. It does not work when you go in and Edit an existing set.
We recommend that you always save your work every so often, regardless, especially when editing an existing set.
