Reviewing old lessons without rereading everything

Choose old work from errors and recall results, then recheck with new cues after a gap.

Choose an old task rather than a whole volume

Choose a recurring error, something needed soon or a failed recall item. If words are weak but patterns stable, test word retrieval instead of repeating the whole lesson. At Lesson 20, use a recheck list rather than rereading Lessons 1–19 every day.

Attempt before reading the explanation

After an explanation makes sense, hide it and attempt the task. Recheck after another study interval; next-day practice can be a starting point, then adapt to results rather than assuming one ideal spacing for everyone. Inspect recurring causes instead of resetting all progress.

Change information to test transfer

After correct familiar answers a week later, change a name, time or question. Record the original and changed cues plus error reason. Keep only unstable items on the immediate list. Old and new tasks may share a pattern without creating a second full schedule.

Example

Recheck card: the original changed a place; the new cue distinguishes being there from doing something there. Answer first, then explain に/で.

Check your understanding

Turn one old mistake into a new-information question and answer without the book.

Explanation

A reasoned response to changed information is stronger evidence than recall of the original answer.
