Yes! You may reset your proficiency ratings for a flashcard deck using the link at the bottom of the proficiency indicator box, which is located to the right of all flashcards.
This makes it possible to go through a completed flashcard deck from the very beginning, which may be helpful for students who may need to refresh their understanding.
This functionality is also available in the app. Click the three dots located at the top right side of the screen, and then select Reset Proficiency.
If you have any questions, please get in touch! We're always happy to help.
