Brainscape flashcards' confidence ratings are meant to evolve over time. Usually, you gradually upgrade your 1s and 2s toward 4s and 5s, as you learn the concepts better and better. Occasionally, you downgrade your 4s and 5s to a 1 or a 2, as you realize that perhaps you did not know a concept as well as you originally thought you did.
But what if you feel like you over-confidently rated all the flashcards in a given Deck or Class, and you aren't seeing the 5s nearly as much as you should be?
For this purpose, we created the Reset Stats feature. In both the website and the iOS app, you can reset a specified group of flashcards back to a confidence rating of "0", as if you'd never studied them at all.
Simply click the Options button next to a Deck on your Class screen (or, in the iOS app, tap a Deck to pop up its Options menu), and select "Reset Confidences". All the flashcards in this Deck will be reset to 0.
If you want to reset stats for all flashcards in an entire Class, then click or tap the Options button near the Class title, and choose "Reset Confidences." Your Class is now as good as new!
