Spaced repetition is all about optimizing your time invested in learning. Spend more time on items that give you trouble and less time on the simpler ones.
This process usually works well but if you’re like me you might have noticed that some items you get consistently wrong. A specific kanji or vocab that you have a especially hard time remembering and that is always like a thorn on your side.
Anki define these elements as “leeches” and I think the metaphor is quite apt, they’re the items that consume most of your learning time.
It would be nice to have a way of spending more time on these “leech” items.
The feature could look like this:
- The user has the option to create a custom review queue (like the custom decks in anki)
- It would show you all the cards that you got wrong more than n times.
- You would need to answer the cards correctly more than once to be able to move on ( the exact threshold could be user defined)
- These reviews would not affect your main reviews and would only serve as a way to memorize the nastier elements of your collection
