Babbel’s Review feature is based on the proven method of spaced repetition, and this is used in our product via Stages. Depending on which Stage of the process you’re at with a piece of vocabulary, you’ll see an item more or less often.
How many Stages are there?
There are six Stages in total, with Stage 1 being a completely new piece of vocabulary, and Stage 6 when it’s in your long-term memory. Each time you review something correctly, it moves up to the next Stage. Here’s the detailed breakdown:
- If you get something correct, the word or phrase moves up one Stage and becomes due again in 4 to 180 days (depending on the new Stage)
- If you make one mistake, the item stays on the same Stage and becomes due again the next day
- If you make more than one mistake, the word or phrase moves down a Stage and becomes due again immediately
In short, words and phrases that come easily to you will end up at a higher Stage and need to be reviewed less. Items you have more difficulty with will have to be reviewed more often until they make it into your long-term memory.
