Many students revise by rereading their notebook again and again. It feels reassuring, because after a few readings the text seems familiar. But recognising a lesson is not the same as being able to recall it, or to use it in an exercise. The methods below have one thing in common: they make your memory work actively, instead of just rereading.
1. Make your own revision sheets
A good revision sheet fits on one page and summarises a chapter in your own words. It is not a copy of the lesson: it is a selection. It holds the definitions, the formulas or rules, a typical example and the traps to avoid.
- A clear title: subject, chapter, class.
- The essentials at the top: the three to five ideas you must remember.
- A worked example: it shows how the idea is applied.
- My mistakes: what you have already got wrong.
Writing the sheet is already revision: choosing what matters forces you to understand. A sheet copied from a classmate is far less useful.
2. Test yourself instead of rereading
This is the most effective method and the most neglected. After reading a lesson, close your notebook and try to say or write down what you remember. Only then compare with the lesson. Whatever was missing is exactly what you need to review.
A few ways to test yourself:
- Write questions on the back of the sheet and the answers on the front.
- Explain the lesson out loud, as if presenting it to a classmate.
- Do a short quiz or an exercise without looking at the solution.
- Redraw a diagram or a map from memory, then check it.
Getting things wrong during these tests is not failure: it is when you learn the most.
3. Space out your revision
We quickly forget what we have just learned, especially in the first few days. Each time you review an idea just as it is starting to fade, you remember it for longer. That is the principle of spaced repetition.
A simple rhythm for a new lesson:
| When | What | Time |
|---|---|---|
| The same evening | Reread and complete the sheet | 10 to 15 min |
| The next day | Test yourself without the sheet | 5 to 10 min |
| One week later | Test yourself, redo an exercise | 10 min |
| One month later | Test yourself on the whole chapter | 15 min |
This rhythm takes little time each day, and it saves you from having to relearn everything before the end-of-term tests.
4. Practise on exam-style exercises
Understanding a lesson does not guarantee you will succeed on an exam exercise. Exam papers mix chapters, use particular wording and impose a time limit. So you need to practise them.
- Start with simple exercises, one chapter at a time.
- Then move on to exercises that mix several chapters.
- Finish with complete, timed papers, in a quiet place.
- Always mark your work, then write in your mistakes log what you got wrong and why.
Varying the types of exercise also helps: alternating calculations, problems and lesson questions in one session forces you to recognise which method to use, exactly as on exam day.
5. Organise your time
Good organisation prevents nights of panic. It comes down to three tools:
A weekly plan
Identify the fixed slots when you can work (after school, before dinner, Saturday morning…). Give each one a subject. Also keep some free slots to catch up if you fall behind.
Short, focused sessions
Work in blocks of twenty-five to forty minutes, followed by a short five-minute break. During a block, your phone is out of reach and on silent. After three or four blocks, take a real break.
A list of precise tasks
"Revise maths" is too vague. "Redo exercises 3 and 4 on equations" is a task you can start and finish. Tick off what is done: watching your list shrink is motivating.
6. Sleep, move, eat
Sleep is not wasted time: it is during the night that the brain consolidates what was learned during the day. A student who sleeps too little remembers less and concentrates less well. Before an exam, a good night is worth more than an extra hour of revision.
- Keep regular bedtimes and waking times, even at weekends.
- Put screens away at least half an hour before sleeping.
- Move a little every day: walking, playing football, dancing. Physical activity helps concentration.
- Eat breakfast and drink water during the day, especially on exam days.
Putting it all together: a typical evening
- 15 minutes: review the day's lessons and complete your sheets.
- 30 minutes: do tomorrow's homework.
- 5 minutes break.
- 20 minutes: test yourself on the topics your plan schedules (yesterday's, last week's, last month's).
- 5 minutes: pack your bag and write tomorrow's list.
It is not long. Regularity makes the difference, far more than duration.
