The three techniques worth your time
- Retrieval practice: recalling information from memory with little or no prompting, for example a quiz, flashcards, a blank-page brain dump or a past-paper question. The Education Endowment Foundation (EEF) review of cognitive science in the classroom found this one of the most promising approaches, and a major review by Dunlosky and colleagues (2013) rated practice testing as "high utility".
- Spaced practice: spreading revision of a topic over several sessions with gaps in between, rather than cramming it in one go. Dunlosky's review also rated this high utility. In practice, it means revisiting a topic after a day or two, then a week, then a few weeks.
- Interleaving: mixing different topics or question types within a session, so you have to choose the right method each time. The EEF notes that the evidence is strongest in maths and less certain in other subjects, so use it mainly for maths and science calculations.
- What to cut back: rereading and highlighting feel productive but were rated low utility by Dunlosky's review. If you reread, finish by closing the book and writing down what you remember.
How to build your timetable
- List every GCSE you are sitting and every paper, with its date. Check your exam board timetable; the summer 2027 series runs from May until the last common exam on 18 June 2027.
- Under each subject, list the topics from the specification. Rate each one red, amber or green based on your latest mock or a short practice test.
- Block out the time you genuinely have each week: school, travel, sleep, meals, exercise and one evening off. Revision sessions of 30 to 45 minutes with short breaks work well for most students.
- Fill each session with one retrieval task, not just a topic name. "Biology: cell transport, 15 flashcards then 3 exam questions" is a plan; "Biology" is not.
- Schedule every topic at least three times across the plan, with gaps between, and give red topics extra slots.
- Keep a mistakes log. Each time you get a question wrong, write down why and add that topic to the next week's plan.
- Review the timetable every Sunday. Move topics between colours as your practice scores change.
A 12-week plan for summer 2027
| Weeks | Focus | What to do each week |
|---|---|---|
| 1 to 2 | Audit and foundations | Take a short diagnostic test in each subject. Make flashcards for key facts, formulas, quotations and definitions. Start daily 10-minute flashcard reviews. |
| 3 to 4 | Red topics, first pass | Two red topics per subject per week: relearn briefly, then answer exam questions on them. Retest last week's topics before starting new ones. |
| 5 to 6 | Amber topics and mixed practice | Work through amber topics. Add one mixed (interleaved) question set per week in maths and science. Do one timed section of a past paper per subject. |
| 7 | First full papers | One full past paper per main subject under timed conditions. Mark it with the mark scheme and log every lost mark by topic. |
| 8 to 9 | Fix the gaps | Spend most sessions on the topics in your mistakes log. Practise extended answers (6-mark science, English and history essays) against the mark scheme. |
| 10 | Second round of full papers | Another full timed paper per subject. Compare with week 7 to see which topics have improved. |
| 11 | Exam technique | Timed questions only. Practise planning long answers in 3 to 5 minutes. Keep daily flashcards going. |
| 12 | Final review | Light retrieval: flashcards, brain dumps and a few questions per topic. Sleep properly, keep to normal routines and check your exam timetable and equipment. |

Using past papers well
- Use your own exam board's papers and mark schemes, and the right tier for maths and science.
- Start with single questions on topics you have just revised, then move to full papers under timed conditions from about week 7.
- Mark honestly with the mark scheme, then read the examiner's report for common mistakes.
- Do not memorise answers to specific questions. Boards write new questions every series, so focus on the method.
- Grade boundaries change every series, so use old boundaries only as a rough guide to where you are.
Free practice for each subject
Short, timed question sets are an easy way to add retrieval practice to every day of your plan. Each subject page has free questions with worked explanations: GCSE Maths practice test, GCSE English Language practice test, GCSE Combined Science practice test, GCSE Biology practice test, GCSE Chemistry practice test, GCSE Physics practice test, GCSE Computer Science practice test, GCSE Geography practice test and GCSE History practice test.

Look after the basics
Sleep, regular meals and some exercise help you remember what you revise. Avoid all-night sessions before exams. If revision is making you very anxious, talk to a teacher, your form tutor or a parent early: schools can help with planning and, where appropriate, access arrangements.
Frequently asked questions
When should I start revising for GCSEs?
Around 12 weeks before your first exam gives time to cover every topic at least three times with gaps between. Starting earlier with short weekly retrieval sessions is even better.
How many hours a day should I revise?
There is no magic number. Two to three focused sessions of 30 to 45 minutes on school days, and a little more at weekends and in the Easter holidays, works for many students. Quality of practice matters more than hours.
Are flashcards a good way to revise?
Yes, if you use them to test yourself: look at the front, say or write the answer, then check. Making the cards is only the first step.
Should I revise one subject a day or mix them?
Mix them. Two or three subjects a day lets you space each subject out, and mixing question types within maths and science gives you interleaved practice.
How many past papers should I do?
Quality beats quantity. One or two full timed papers per subject, properly marked and followed up, plus regular single questions, is more useful than rushing through many.
