The Character Coverage section of the dashboard breaks down the characters you’ve learned into HSK levels.
Each card corresponds to the HSK level. You can see exactly how many characters you’ve learned against the total characters we have for that HSK level.
This is also translated into a percentage to get a better visual of how far along you are.
In the above figure, you can see that this user has learned 300 characters from HSK-1, and 23 characters from HSK-2.
