An archive is most useful when it records why an answer was hard. A long list of completed grids alone does not improve recall.
Tag the missed clue
Use one of four tags: spelling, vocabulary, identity, or event context. The tag determines what to review.
- Write the clue and final answer.
- Add one-sentence context.
- Link the authoritative source.
Revisit on a delay
Review after a day, a week, and a month. Delayed recall is more informative than immediately rereading the answer.
- Cover the answer first.
- Explain the clue aloud.
- Stop reviewing items that are consistently easy.
Keep the archive compact
Save only facts that changed your understanding or repeatedly slowed you down. A selective notebook stays usable.
- Limit each paper to three notes.
- Prefer context over isolated dates.
- Remove duplicate lessons.
