Each time you save a LingQ it is added to your database of LingQs. These words are then sent to you for review in the LingQs of the Day email.
If you miss a day or two, you may be tempted to keep that email lying around your inbox. But not to worry! You can access the LingQs of the Day lists from the past two weeks right from the Vocabulary page. Just click on the arrow next to “Due for Review (SRS)” and choose the date that you want to view.
If you have some extra time and want to do more review, you can also click directly on “Due for Review (SRS)” in order to view all of your LingQs that are scheduled for review.
