Reference · Retention
A spaced schedule to turn this course's fluency into long-term memory.
You learn a thing once; you keep it by retrieving it at widening intervals, just as it starts to fade. Re-take the interleaved quiz on this schedule — each pass is quick, and the effort of recall is what cements it.
| When | Do | Goal |
|---|---|---|
| Today | Take the mixed quiz; note every miss. | Find weak spots. |
| +3 days | Re-take from memory; reread the glossary entry for any miss. | First consolidation. |
| +1 week | Re-take; attempt the synthesis design out loud. | Combine pillars. |
| +1 month | Re-take cold; teach one concept to someone else. | Durable storage strength. |
| +3 months | Skim cheat sheets; re-take only weak pillars. | Maintenance. |
Retrieve before you review — always try to recall before reopening the notes. Space it out — a miss re-tested tomorrow beats five reads today. Interleave — mix pillars so you practice choosing the concept, not just reciting it. Teach it — explaining a concept aloud is the strongest test of all.
