Study radicals, kanji and vocabulary in step with the official textbook — and let spaced repetition bring each item back right before you'd forget it.
Each item returns right before you'd forget it, so reviews stay short and what you learn actually sticks.
Tricky items come back more often than easy ones — your time goes where it's needed most.
Pick your chapter to unlock exactly the radicals, kanji and words your class is working through.
