We are working on improving the amount of data that is surfaced to everyone, to give them a better idea of how much they have learned so far, and more details about what they have learned.
A first step towards this is adding the HSK level of each item we teach, viewable view the item page itself. Here we can see the HSK level on the page for 好:
You can read more about how the level is calculated for non-standard items like components and sounds on our documentation page.
Next up is surfacing HSK-related statistics and on the dashboard itself.
