What is spaced revision?
Spaced revision separates encounters with material over time. It can be combined with recall: try to retrieve what you learned, check it and return on a later day. EEF’s cognitive science review considers spaced learning among several approaches and cautions against assuming that every classroom application works equally well.
There is no single review calendar on this page that is right for every subject or student. The gap needs to fit what you know, the task and the time before the assessment.
A flexible example across two weeks
Suppose you have completed an inheritance topic. On Monday, attempt a short explanation and check it. Later in the week, try a question without the notes. The following week, mix it with a question from another topic and review any errors.
The important feature is returning after a gap and checking the attempt. Monday, Thursday and the following Tuesday are illustrative choices, not a scientifically prescribed sequence.
| Return | Task | What to record |
|---|---|---|
| First session | Recall a process, then check the notes | The missing or incorrect steps |
| Later that week | Attempt a related question | Whether you can use the idea |
| Following week | Retry alongside an earlier topic | What still needs explanation or practice |
Adjust the gap using what happened
If you cannot begin the task, return to the explanation and ask for help where needed. Repeating a question you do not understand does not resolve the underlying gap.
If the task is easy, choose a more demanding application or a longer interval before another check. Keep a short record so decisions come from an attempt rather than from how familiar the page looks.
Keep several subjects in view
A broad GCSE timetable can make it easy to leave a subject untouched for several weeks. Reserve small return sessions before filling the remaining time with the nearest paper.
At A-level, revisit earlier course material while current teaching continues. Group related tasks when that helps you understand a connection, but avoid a complicated review system that takes longer to maintain than to use.
Use the plan to make room for return visits
Write a later attempt into your weekly timetable and give it a narrow purpose. “Retry the question I missed on Monday” is more useful than “revise more”.
Pace distributes your chosen time across subjects and records completed effort. It is not a spaced-repetition algorithm for individual flashcards or proof that a topic has been mastered. You choose the questions and interpret the feedback.
Practical answers
Questions before you start
Should I use a 1–3–7-day schedule?
It can be an organisational starting point, but it is not a universal rule. Adjust the gap to your understanding, the task and the assessment date.
Can I combine spaced revision with past papers?
Yes. Return to selected questions or skills after reviewing earlier errors. Use a fresh question where possible so you practise the reasoning rather than remember the answer.
