Keep-Word Note

[Forgetting Theory]According to Ebbinghauss theory of forgetting, over time, we gradually forget what we have learned.[How to overcome oblivion?]"Review" slows the rate of forgetting. And if you "repeat" a review, its more likely to become long-term memory.The Keep app notifies you when you need to review. Now, dont worry about when youre going to do a review. Just add a word and Keep will schedule a review for you.[Memory Level]The first word added has a memory level of 1. When reviewing, if you remember, the level increases by 1. If you cant remember, go back to level 1. For example, if you cant remember from level 3, it will be level 1. Level 6 is the last, and level 6 is the long-term memory word. Make it up to level 6.[Review scheduling according to memory level]Memory level 1: after 9 hoursMemory Level 2: After 2 daysMemory Level 3: After 7 daysMemory Level 4: After 14 daysMemory level 5: After 32 days
