Come back to material on a later day instead of relying on one long session.

**The number:** Spacing review: 317 experiments on study timing and verbal recall ([Psychological Bulletin, 2006](https://pubmed.ncbi.nlm.nih.gov/16719566/))

## The evidence

- How sure: Certainty of evidence: Not rated. Measured in the general population; we say so because ADHD trials of this do not exist or are too small.
- Evidence grade: B. Grade B: trials in ADHD with low certainty, or strong general health evidence with a sourced reason it matters more with ADHD.
- Basis: General learning meta-analysis; 317 experiments, no ADHD-specific effect and no formal GRADE rating.
- Benefit: 45/100. The benefit score is an editorial prioritization for the general list, weighted by certainty. It is not a prediction of what will happen for you.

## Why it matters

A general-population review covering 317 experiments found that spacing study episodes affects later verbal recall, with useful intervals depending on how long you need to remember. It does not establish an ADHD-specific spacing schedule or one best gap for every subject. NHS information describes planning and concentration difficulties in ADHD, so putting a small revisit in the calendar can make this learning strategy easier to use.

## How to do it

1. Pick one small topic you need to remember after today.
2. Plan another short look at it on a later day.
3. When you come back, try to recall it before you check.
4. Set the next gap by your deadline and by how much you remembered.

## Putting it into practice

### Start now

- 1 minute: Pick one thing you want to remember next week and when you could look at it again.
- 5 minutes: Add one short revisit of a current topic to your calendar.
- 15 minutes: Review an earlier topic, check what you recalled and arrange its next revisit.
- 30 minutes: Split one upcoming topic into small sessions across the time available before your deadline.

### What it looks like

- Revisit a small set of terms on another day instead of repeating them only in one sitting.
- Put a short return to yesterday's topic into the calendar before you close your notes.

### Common mistakes

- A rigid schedule adds more admin than learning; schedule only the next revisit.
- Spacing can slide into passive rereading. Recall and correct when you come back.

### A structured start

**Return before the deadline**

1. Choose a small amount of material.
2. Schedule and complete a later revisit.
3. Adjust the next interval using what you remembered.
