Set difficulty by CEFR level rather than school grade, and review saved words with spaced repetition.
Difficulty used to be a school reading grade, which means nothing if you're learning Portuguese in Osaka. It's now a CEFR slider from A1 to C2 — the standard the rest of language learning already uses.
Saved words can now be reviewed with spaced repetition: each one comes back right before you'd have forgotten it, and the interval stretches every time you get it right. You can also drill any group on demand rather than waiting for the schedule.
