Starting revision can feel harder than the revision itself. You open your notes, realise how much there is to cover, and spend the next hour deciding where to begin.
If you have been putting revision off, start with one small topic, test what you know, and use your mistakes to choose your next task. You do not need to organise every folder or finish a perfect timetable before you begin.
Starting late limits how much you can cover, but the time you have left can still be useful. Whether you are preparing for GCSEs, IGCSEs, A levels or IB exams, these ten steps will help you begin and make your revision more purposeful.
The 10 ways to get going
- Make your first task small and specific.
- Check exactly what your exam covers.
- Find your gaps with a short test.
- Choose priorities that fit the time you have.
- Make a timetable you can realistically follow.
- Test your memory instead of only rereading.
- Use flashcards for information you need to recall.
- Practise what your exam actually asks you to do.
- Keep a short error log, and act on it.
- Make starting easier and get specific help.
Need to start right now? Try this 30-minute session
Choose a topic you have already been taught.
| Time | What to do |
|---|---|
| First 2 minutes | Put your phone out of reach. Open one topic and a few relevant questions |
| Next 5 minutes | Without your notes, answer three short questions or write what you remember |
| Next 8 minutes | Check your answers. Read a short explanation of the gaps you found |
| Next 10 minutes | Close your notes and attempt questions on those gaps |
| Final 5 minutes | Mark your work, record one correction, and choose when to revisit the topic |
Tip
If 30 minutes feels like too much, start with one question and its correction. That gives you a clear task you can finish today. If motivation is the real problem, see how to revise when you feel lazy.
Make your first task small and specific
"Revise chemistry" is hard to start because it does not tell you what to do or when you are finished. Replace it with a specific action:
| Subject | Specific first task |
|---|---|
| Maths | Answer five questions on solving linear equations |
| Biology | Explain diffusion without notes, then check your explanation |
| History | Plan one essay answer using three pieces of evidence |
| English Literature | Write one analytical paragraph about a character |
| Languages | Recall ten useful words, then use five in sentences |
Choose a task that fits into 10–20 minutes. You can carry on afterwards, but you only need to commit to that first task.
Try today
Complete this sentence: "For the next 15 minutes, I will…" Make the ending something you can check, such as "answer and mark five equations".
Check exactly what your exam covers
Before using revision resources, confirm:
- your qualification and exam board;
- your specification or syllabus code;
- your tier, where relevant;
- your set texts and optional topics;
- what each paper assesses.
Watch out
A resource for a different course might miss content you need, or include material you will not be assessed on.
Use the current specification or syllabus to make a simple checklist, breaking large headings into manageable skills.
Example
"Fractions" could become:
- add and subtract fractions;
- multiply and divide fractions;
- convert between mixed numbers and improper fractions;
- solve problems involving fractions.
The specification lists the content and skills assessed. It does not mean every question will look familiar: you may need to apply your knowledge to an unfamiliar source, text, experiment or situation.
Try today
Turn one specification section into five to ten short tasks. Ask your teacher if you are unsure which options your class studies.
Find your gaps with a short test
You do not need to finish revising before attempting questions. A short test shows you where to begin.
Choose a few questions on content you have been taught. Attempt them without notes, then mark them, and label each topic:
| Label | What it means | What to do next |
|---|---|---|
| Red | You cannot explain the idea or begin the question | Learn it in small steps using an explanation or worked example |
| Amber | You understand some of it but need prompts or make mistakes | Practise on your own and correct specific errors |
| Green | You can answer accurately without help | Revisit later and practise applying it in mixed questions |
These labels are temporary. Update them when your performance changes.
Remember
A topic feeling familiar is not enough to make it green. Check whether you can answer questions with your notes closed.
If a whole paper feels overwhelming, start with one question or a short section. If the topic is completely new, learn the basics before expecting yourself to answer independently. Starley's practice questions are organised by topic, which makes short tests quick to set up.
Choose priorities that fit the time you have
When you feel behind, it is tempting to spend all your time on your favourite subject or start rewriting the first chapter of every textbook. Instead, weigh up four things:
- Urgency: which exam is soonest?
- Your gaps: where are you losing marks?
- Foundations: which skills help you answer several types of question?
- Assessment requirements: which topics and skills belong on each paper?
Example
Improving weak algebra may help across several parts of a maths paper. If you know your history evidence but struggle to use it, practising arguments and paragraphs may be more useful than memorising more dates.
Watch out
Do not use past papers to guess which topics you can safely ignore. They show you the assessment style, but they cannot reliably tell you what will appear next.
Try today
Choose three priorities for the week. Give each a specific task and a place in your schedule.
Make a timetable you can realistically follow
A revision timetable is useful when it tells you what to do next. Start with your existing commitments, including school, travel, work, meals and rest. Then add manageable study blocks with clear tasks.
| Day | Task | How you will check it |
|---|---|---|
| Monday | Practise balancing chemical equations | Mark ten questions and correct errors |
| Tuesday | Plan a history essay about causes | Check that each paragraph supports the argument |
| Wednesday | Revisit Monday's errors | Attempt new equations without notes |
| Thursday | Write an English analytical paragraph | Check the assessment criteria and ask for feedback |
| Friday | Complete a mixed maths question set | Identify two skills to work on next week |
Leave space for tasks that take longer than expected.
Tip
If you miss a session, move the most important unfinished task into your next free slot. Avoid doubling everything tomorrow and making the plan harder to follow.
Try today
Plan your next three sessions. Expand the timetable once you know what is manageable. For full examples, see our GCSE Maths revision timetable and A Level revision timetable guides.
Test your memory instead of only rereading
Reading notes can help you understand a topic. To check whether you can remember it, close them and try to produce an answer.
This is called retrieval practice, often described as active recall. A 2022 review in Nature Reviews Psychology found strong support for retrieving learned information and revisiting it over time, and the Learning Scientists explain retrieval practice in plain terms for students. You could:
- answer questions without notes;
- explain a process aloud, then check each step;
- draw and label a diagram from memory;
- write an essay plan without looking at your notes;
- make a mind map from memory, then add missing links in another colour.
Your turn
After studying photosynthesis, close the page and answer:
- What are the reactants and products?
- What conditions are needed?
- How could light intensity affect the rate?
- How would you investigate that effect?
AnswersShow answersHide answers
- Carbon dioxide and water react to form glucose and oxygen.
- Light, chlorophyll and a suitable temperature (as well as carbon dioxide and water).
- Increasing light intensity increases the rate, up to the point where another factor, such as carbon dioxide concentration or temperature, becomes limiting.
- For example, place pondweed at different distances from a lamp and count the oxygen bubbles produced per minute, keeping temperature and carbon dioxide constant.
Then check your answers and repair the gaps.
If you cannot recall much, make the task smaller. Study one short section or one worked example, then try a focused question; retrieval works best with some support when material is new or difficult.
Check
Highlighting can help you pick out important information. Follow it with the question "Can I explain this with the page closed?"
Use flashcards for information you need to recall
Flashcards are useful for definitions, vocabulary, formulae, dates, quotations and short explanations. Keep each card focused on one clear question.
| Less useful card | More useful card |
|---|---|
| "Everything about osmosis" | "What is osmosis?" |
| "The Cold War" | "How did the Berlin Blockade increase tensions?" |
| "This whole textbook page" | "Why does increasing temperature usually increase reaction rate?" |
Answer before turning the card over. If you miss it, check the answer and try again later.
Revisit cards across separate sessions: for example, tomorrow, a few days later and the following week. That is a starting schedule, not a universal rule. Shorten the gap when you keep forgetting and extend it when recall is secure; the Learning Scientists' guide to spaced practice explains why.
Key point
Combine flashcards with application. Remembering a formula does not show that you can choose it, rearrange it or use it in an unfamiliar problem.
Try today
Make five cards from mistakes in your latest question set, then schedule a short review. Starley's flashcards are organised by subject if you want ready-made cards to check against.
Practise what your exam actually asks you to do
Your exam may ask you to calculate, explain, analyse, evaluate, interpret or write under time pressure. Your revision should include those actions. Build up in stages:
- Study a worked example if the method is unfamiliar, and explain why each step is used.
- Attempt similar questions on your own to check your understanding.
- Try mixed questions so you have to decide which method to use.
- Practise timed sections or papers to develop pacing and exam technique.
Use papers that match your course, and check whether older questions are still relevant. Exam boards provide official resources: AQA's past paper finder, for example, includes papers, mark schemes and examiner reports, and Starley's past papers are organised by board and subject.
When marking, look beyond the total score:
- What did the question ask?
- Which part of your answer earned marks?
- What was missing, inaccurate or not explained enough?
- What should you do differently next time?
For essays and extended responses, mark schemes often describe levels of performance rather than one exact answer. Use them alongside teacher feedback to judge your argument, evidence and explanation.
Tip
Examiners' reports can help you spot common mistakes. Turn a relevant comment into a specific action, such as "explain how every piece of evidence supports my argument".
Try today
Attempt one short exam section, mark it, and choose one skill to improve before your next attempt.
Keep a short error log, and act on it
The useful part of marking is deciding what to change.
| Mistake | Possible cause | Next action |
|---|---|---|
| Used the wrong formula | Did not recognise the type of problem | Compare similar question types and practise choosing the method |
| Lost a mark for units | Left the unit out of the final answer | Add a units check to calculation practice |
| Described events in an essay | Did not explain how they supported the argument | Rewrite the paragraph with a clear link to the question |
| Ran out of time | Spent too long on one difficult question | Practise a timed section with a plan for moving on |
Keep the log brief. A correction you revisit is more useful than a detailed table you never open again. After studying the correction:
- Close the answer.
- Redo the question.
- Later, try a different question testing the same skill.
Remember
That final step shows whether you learned the method or only remembered one answer.
Make starting easier and get specific help
Before a session, set out the exact question or resource you will use. Put your phone somewhere you cannot casually reach it and close unrelated tabs.
Try a 20–30-minute study block followed by a short break, then adjust it to your concentration and the task. You do not need to follow one particular timer setting.
Choose one main explanation resource and one source of practice questions. Use what you already have where possible: buying stationery, downloading apps and collecting resources do not need to come first.
Watch out
If you use an AI tool, ask for hints, practice questions or an explanation of a step. Check its output against your course materials, because answers and marking can be wrong. Attempt the work yourself before viewing a complete solution.
When you need help, ask focused questions:
- "I can solve equations with positive numbers, but I get stuck with negatives. Where does my method go wrong?"
- "Does this paragraph explain the evidence clearly enough?"
- "Which part of my answer kept it out of the next mark band?"
If you keep struggling to begin, tell a teacher or someone you trust. They can help you reduce the workload, clarify priorities or find support.
How should you revise if you have left it late?
These are practical starting points, not promises about the grade you will achieve.
| Time left before an exam | Suggested focus |
|---|---|
| Several months | Build broad coverage, revisit learning regularly and gradually increase exam practice |
| Two to four weeks | Identify gaps, repair important foundations and practise questions alongside content revision |
| About one week | Prioritise the next paper, recurring errors and skills you can improve in the time available; include timed sections |
| One or two days | Review essential knowledge, practise a manageable set of questions, check exam arrangements and protect time to rest |
When time is tight, organise revision by paper as well as by subject. Check which content belongs on the next paper so your immediate work is relevant; Starley's exam timetables show every paper by board.
Important
You may not cover everything. Choose deliberately, while recognising that content you leave out could still be assessed. For a day-by-day example, see our final-week GCSE Maths plan and the exam week checklist.
Frequently asked questions
Is it too late to start revision?
Starting earlier gives you more chances to learn and revisit material. Starting now can still help you repair gaps and improve how you answer questions. What is achievable depends on your starting point, the course and the time remaining; no revision plan can guarantee a particular grade.
How many hours should I revise each day?
There is no universal number. Plan around your commitments, concentration and workload. Start with a manageable amount and check whether you are completing useful tasks: track questions answered accurately and mistakes corrected, not just time spent.
Should I make notes or do past papers first?
If you have already learned the topic, try a few questions first to find the gaps, then use notes to repair them. If the content is new or confusing, begin with a short explanation or worked example before practising on your own.
Are videos useful for revision?
They can help explain a difficult idea. Pause to answer a question or predict the next step. Afterwards, close the video and explain the topic or attempt a question yourself; watching alone does not show what you can do independently.
What if I keep forgetting what I revise?
Make the topic smaller, check you understand it, and return to it across separate sessions. Test yourself before checking the answer. If a specific idea keeps causing problems, ask for an explanation rather than repeatedly memorising words you do not understand.
What if I miss a day?
Resume with one manageable task. Move an important unfinished task to your next available session and adjust the plan. You do not need to restart your whole timetable.
