Most students revise the way that feels most productive: re-reading notes, highlighting and copying things out neatly. Unfortunately, research suggests these are among the least effective ways to learn. The good news is that a few well-evidenced techniques make a big difference, and they work for GCSEs and A-Levels alike.
Start with what the exam actually asks
Before making flashcards or timetables, find out exactly what your child will be examined on.
- The specification. Each exam board publishes a specification for every subject, listing everything that can be assessed. It makes an ideal revision checklist — a simple red, amber and green rating for each topic shows where to focus.
- Past papers and mark schemes. These show the style of questions and, crucially, what examiners give marks for.
- Examiners' reports. Published after each exam series, they explain where students lost marks — often the most useful revision document nobody reads.
Use retrieval practice, not re-reading
Re-reading notes feels productive because the material becomes familiar, but recognising something isn't the same as being able to recall it under exam conditions. Retrieval practice — recalling information without looking — strengthens memory far more. Effective ways to do it include:
- flashcards, with the question on one side and the answer on the other;
- writing down everything you can remember about a topic on a blank page, then checking your notes for gaps;
- answering past-paper questions without notes;
- explaining a topic out loud to someone else.
It should feel like hard work. That effort is what makes it effective.
Space it out
Cramming can get information into memory for the next day, but it fades quickly. Spacing — returning to each topic several times, with gaps of days and then weeks in between — produces much longer-lasting learning. In practice, that means a revision timetable that cycles through subjects and topics, rather than finishing one subject before starting the next.
Mix topics up
In subjects like maths and the sciences, practising one type of question over and over can make students good at that question type without learning when to use it. Interleaving — mixing different topics and question types in one session — is harder, but it builds the skill exams actually test: recognising which method a question needs.
Practise under exam conditions
As exams approach, complete full past papers in the time allowed and mark them honestly using the mark scheme. Keep an error log of every question that went wrong and why — a gap in knowledge, a misread question or a slip in working — and revisit those topics. Exam technique, from timing to the structure of longer answers, improves with practice like any other skill.
Build a realistic plan
- Start early. Light, regular review can begin well before exam year. For structured revision, aim to start several months before the exams; many students build their timetable after their mock exams.
- Work in focused blocks. Short sessions with a clear goal and regular breaks are more productive than long, unfocused hours.
- Plan backwards. Work out how many weeks remain, list the topics for each subject, and make sure everything is covered at least twice.
- Leave slack. A timetable that's too ambitious is quickly abandoned. Build in time to catch up and to rest.
Look after sleep, food and exercise
Sleep plays an important role in consolidating memory, so late-night cramming often backfires. Regular meals, time outdoors and exercise all help concentration and mood during a stressful period.
How parents can help
- Provide a calm space to work, with phones out of reach during revision sessions.
- Help with retrieval practice — quizzing your child from flashcards is one of the most useful things you can do, even if you don't know the subject.
- Encourage routine, but let your child own their plan.
- Notice stress early, and keep perspective: exams matter, but your child's wellbeing matters more.
- Talk to the school if you're worried; teachers can often suggest priorities or extra support.
When extra support helps
Some students need more than a good plan: a gap in understanding that self-study can't close, difficulty with exam technique, or simply the accountability of a weekly session. A tutor who knows the specification can target exactly what's holding a student back.
