-
Three levels decide which words and sentences each lesson uses. Level 1 keeps to the most common ones, and you can change it later.
-
The episode’s hardest words come up as flashcards, with the reading and meaning on the back. The ones you miss come back until you know them.
-
Your English subtitles stay on, and only the lesson’s Japanese sentences show up. Watch as usual, or skip between them in the side panel.
-
Ten of those sentences come back as questions. Fill in a missing word, or choose what a highlighted word means. Seven right answers pass.
Passed with 9 of 10.

Passing the quiz unlocks the lesson for the next episode. If you don’t pass, you can take it again.
