Can you recall cao without looking? Try three cards from “Tone Families” and see how LENGO decides when to show a word again.
How does LENGO decide what I practice?
Every word has a strength. New words come first, then the words that are due: a weak word comes back after 10 minutes, a strong one after three days to a week. A right answer makes the wait longer, a wrong one brings the word back sooner.
How many new words do I learn a day?
Seven to start with. You can set anything from 3 to 20 new words a day.
