Revision techniques that actually work for A-Level and GCSE

What the evidence says about revision methods, and how to use each one.

What the evidence says

Most students reread notes, highlight and copy things out. Those methods feel comfortable but give a weak return. In a large review published in 2013, Dunlosky and colleagues rated ten common learning techniques. Practice testing and distributed practice got the highest utility rating. Summarising, highlighting and rereading were among the lowest rated.

The Education Endowment Foundation (EEF) adds a useful caution. Its review of cognitive science in classrooms says these approaches can improve learning, but the evidence on how best to apply them across ages and subjects is still limited. So treat the techniques below as strong starting points, then check whether they work for you by tracking your own scores.

Technique	What you do	Evidence rating or note
Retrieval practice	Close the notes and write down what you remember	Practice testing rated high utility (Dunlosky 2013)
Spaced practice	Return to topics over days and weeks	Distributed practice rated high utility (Dunlosky 2013)
Interleaving	Mix topic types within one session	EEF says classroom evidence is still developing
Past papers	Answer real questions under timed conditions	Recommended by AQA
Rereading, highlighting	Go over notes again	Rated low utility (Dunlosky 2013)

Retrieval practice

Retrieval means pulling information out of your memory instead of putting it in again. The EEF describes how retrieving knowledge brings it back into working memory, and practising this makes the knowledge easier to recall later.

How to do it

Pick a topic and read it once.
Close everything. Write down everything you remember, as a list or a mind map.
Open your notes and mark what you missed in a different colour.
Repeat on the missed parts only.

Other formats work too: flashcards, a blank-page brain dump, or asking someone to quiz you. Whatever format you choose, the effort of recalling is what helps, so avoid peeking.

Spaced practice

Spacing means splitting study of a topic across several sessions with gaps in between. A gap makes recall harder, and that difficulty is useful.

Revisit a topic one or two days after you first learn it.
Test it again about a week later.
Test it again a few weeks later, closer to the exam.

The gaps above are a sensible rule of thumb, not a figure from the research. If you forget most of a topic at a check, shorten the gap next time. Our GCSE revision timetable guide shows how to build these repeat visits into a weekly plan.

Interleaving

Interleaving means mixing different kinds of problem in one session rather than doing twenty of the same type. In maths, that might be a set of questions covering algebra, ratio and geometry together. The benefit is that you must decide which method fits each question, which is exactly what the exam asks. It feels slower and messier than repeating one type, which is normal. Because the EEF says evidence on applying it across subjects is still developing, use it as one tool alongside retrieval and spacing rather than a replacement.

Past papers, mark schemes and examiner reports

Past papers

AQA advises answering past papers under exam conditions to build exam writing skills. Time yourself, use only what you are allowed in the exam, and do not pause to check. AQA's past paper finder shows only papers for the current specification, so check that your paper matches your course. If a specification is new, boards publish specimen papers instead.

Mark schemes

A mark scheme shows how examiners award marks, and AQA describes it as a tool that helps examiners mark consistently. Use it after every paper:

Mark your answers strictly.
For each lost mark, write why: missing knowledge, misread question, or weak technique.
Rewrite one answer so it earns full marks.

Keep a running error log. After three papers, patterns appear, and those patterns tell you what to put in next week's timetable.

Examiner reports

Boards also publish reports on each exam, which give general comments on how candidates answered. AQA makes them available to schools the day before results day, and its public website carries most of them later. For the summer 2026 series, AQA lists 9 July 2027 for public release, so reports from older series are the ones you can read now. Look for repeated mistakes, such as ignoring command words, and make a checklist from them. Not every small subject component has a report.

See AQA's page on what is available when for current release dates, and check your own board's website if you are not with AQA.

Check your own revision

The EEF's guidance on metacognition focuses on planning, monitoring and evaluating your learning. You can do that in a few minutes:

Plan: which topic and which technique?
Monitor: can I answer questions without notes?
Evaluate: what did my score show, and what changes next session?

Write the answers in your error log. Do not confuse feeling familiar with a topic with being able to do the question.

Putting it into a week

Use a simple pattern: learn a topic once early in the week, run a retrieval session later in the week, then a timed past paper question on the weekend. Pair it with your education hub routines, and see what to do on results day for later in the year. For more study guides, visit the guides hub. If you are also getting ready for interviews, the STAR interview technique uses the same practise-then-review habit.
