What this video covers
The spacing effect is the finding that we remember things far better when study is spread out over time than when it's crammed into one session. The same total effort, distributed across days, builds much more durable memory than the same minutes done all at once - which is why last-minute cramming fades so fast.
Crammed into one go, the facts spike then fall away fast. Spread the same study across days and recall holds up - look at the gap in the curves. That's the spacing effect: distributed practice beats massed practice for durable memory. Whenever you need something to last, don't pile it into one session; space it out and bring it back.
