A 25-minute retrieval session

A study block fails in a boring way: you open everything, reread the easiest page, and stop when the timer does. A retrieval session has one job. Produce answers that are not on the screen, then repair a single miss before you add anything new.

The chart below is a plan, not an experiment. Twenty-five minutes is long enough to finish and short enough to start on a school night.

Why this method works

Rereading raises confidence in the same sitting and loses ground over a week, which is the pattern in the testing-effect crossover. A short covered-back block spends the minutes on the harder, more useful act. One repaired miss beats a highlight on twelve pages you will not be asked to produce.

Clear dues before new cards. A pile of unseen cards feels like progress and quietly builds a queue you will not clear. The session is done when the due pile is quieter, not when a generator has drafted more.

Timed session

1. 2 minutes — choose the due pile. Open Study Lab. Stay on cards that are due. If nothing is due, take six older cards, not a fresh import.
2. 12 minutes — cover the back. Flip, four-tile quiz, or fill the blank. Say or type the answer before you reveal it. Rate Again, Hard, Good, or Easy honestly. Do not look up the line “just to check” before you have tried.
3. 6 minutes — name one miss. Pick the card you could not produce. Write whether you forgot a fact or forgot the method. One sentence is enough.
4. 5 minutes — redrill that miss. Cover it again. If it was a fact, say the back in your own words. If it was a method, write the first step, then the rest. Stop. Do not start a second topic.

What to have in front of you

• The due pile, not the whole library.
• A pen if the answer is a worked line. Typing is fine for a short back.
• The book closed until the check minute.

Pitfalls

• Starting with “generate more cards” when yesterday’s pile is still red.
• Rating Easy because the card felt familiar after you peeked.
• Repairing five misses badly instead of one miss properly. The other four can wait until tomorrow’s dues.

After reviewing your scheduled cards, choose an available practice test in Practice Hub. Written work is marked after you submit it, at assignment feedback. The ratings that set the next gap are explained in what Again, Hard, Good, and Easy schedule.

If the pile is huge

A due pile of two hundred cards will not fit in twelve minutes, and pretending it will is how people flip without thinking. Cap the session. Work the oldest dues first for the twelve minutes, then stop. The rest stay due. They will still be there tomorrow, which is the correct outcome. Adding new cards on top of an uncleared pile is how the queue becomes a second inbox.

If you have no cards yet, do not spend the twenty-five minutes importing. Spend them producing. Take one page you read this week, close it, and write six prompts you failed to answer. Those six are the deck. Review them before you save anything you do not believe. A drafted card you have not checked is someone else’s sentence.

A session you can describe afterwards is the check. “I cleared eight dues, missed the red-blood-cell path, and left the artery card for tomorrow” is a finished block. “I studied biology” is not. Write that one sentence in the margin if it helps you stop. Then close the tab. The next session is another day, which is the spacing result, not a second sitting tonight to make the timer look serious.

Run the block at the same time of day if you can. The method is ordinary on purpose. The chart’s four bars are a ceiling, not a target to beat by studying longer. Longer, here, usually means the book crept back open.

If you finish early, do not fill the spare minutes with a new topic. Sit still or leave. Ending early is a success. The students in the rereading study who kept going until the page felt smooth were the ones who scored 40% a week later. Your spare three minutes are not a debt.
