How does the refresher work?
Your personal vocabulary is classified into six levels: in the first one you’ll find the newest vocabulary; in the second, words and phrases that you’ve already seen once; in the third, words that you already know to some extent. By the sixth level it’s vocabulary that you’ve learned for good, and which should by now be firmly anchored in your long-term memory. Every time you work with a word, it is bumped up or down a level. If you make a mistake with it, that word or phrase will be brought to your attention the next time you visit Babbel. Otherwise, the intervals between the next refresh grow from level to level. At the beginning you’ll refresh a word every three days, but by the time that word reaches the fifth or sixth level you’ll only be refreshing it every 120 days.
