How to revise for KS3 exams: a plan for Years 7 to 9

Revise for KS3 exams by testing yourself on a little material, often, rather than rereading a lot of it once: close the book, try to write down what you know, check, and put the gaps first in the next session. That loop, repeated for short sessions across a few weeks, is the whole method.

There is no national KS3 exam, so what a Year 7, 8 or 9 pupil faces is the school's own end-of-year paper. That changes the stakes in a helpful way. Nothing is being certified; the papers exist to show the school, and the pupil, where the gaps are before GCSE courses start. Revision is therefore not about heroics. It is about building a habit that will still work in Year 10.

Why the usual method underperforms

Ask most 12-year-olds how they revise and you will hear the same three things: read the exercise book again, highlight it, copy it out neatly. They all feel like work. A large review of ten common study techniques (Dunlosky and colleagues, 2013) rated practice testing and spreading study out over time as the most useful, and rated highlighting and rereading as low utility. The reasons are in why rereading and highlighting don't work, but the short version is that familiar-looking notes create a feeling of knowing that an exam does not honour.

The routine: four steps, twenty-five minutes

Here is a session a pupil can run alone. Pick one subject and one topic, for example "fractions" or "the causes of the First World War".

1. Blank page first (5 minutes). With the book shut, write or sketch everything you can remember. Ugly is fine. This is the retrieval step, and it is supposed to feel slightly hard.
2. Check (5 minutes). Open the book or the class notes and mark, in a different colour, what you missed or got wrong. Do not recopy the notes; only mark the gaps.
3. Fix the gaps (10 minutes). Work on the marked items only. Re-learn them, work a question, or explain the idea aloud to a parent.
4. Test the fix (5 minutes). Close the book again and answer two or three questions on exactly those gaps. If you get them, you are done; if not, they head the list for next time.

The detail of step 1 is covered in active recall for 11 to 14 year olds.

Spread it out, and mix it up

The same routine done on five separate days beats five times as long in one go. Research on spacing (for example Cepeda and colleagues' 2006 review of 317 experiments, mostly on recalling word lists and facts) found spaced study led to better later recall than massed study, and that the best gap grows with how long you need to remember. For a school exam a few weeks away, a sensible plan (my suggestion, not a figure from the research) is to return to a topic after a couple of days, then after about a week, rather than cramming it once. The mechanics are in spaced repetition explained for parents.

One suggested four-week shape for Year 8 (a suggestion, not a research-backed schedule):

• Week 1: list every topic the paper covers, by subject. Ask the teacher for the topic list if it was not sent home. Mark each one red, amber or green honestly.
• Weeks 2 and 3: two or three twenty-five-minute sessions a day on different subjects, red topics first.
• Week 4: return to amber and red topics, and do one timed practice question per subject under exam-like conditions.

If you would like a ready-made grid, there is one in a revision timetable for Year 8.

A script for parents

Parents often ask what to actually say. Try this, in a calm voice, at the kitchen table:

"Pick a topic. Tell me the three most important things about it without looking. ... Now check. What did you miss? Right, that's what we do tomorrow."

Notice what this avoids. You are not teaching, you are not correcting line by line, and you are not judging. The pupil does the thinking; you hold the list of gaps. If a gap turns out to be something they do not understand, rather than something they forgot, that is a question for the teacher, a tutor, or a patient explanation, not more repetition.

Where an app can help, and where it cannot

Some of this is fiddly to keep up alone, especially turning lessons into questions and remembering when to return to them. Heddy, a KS3 study companion, does some of the admin: its tutors can turn the session you just had into flashcards, and the review room shows each card's next date under the Again, Good and Easy buttons. It caps reviews at twenty cards a day so the pile stays finishable. But a notebook, a timer and a parent with a list of questions carry out the same method. The method is what matters; any tool is just a way of keeping it going.
