Exam preparation is easier when you have a clear plan and use methods that research shows work well. Starting early and studying actively matter more than long, last-minute sessions.
Key takeaways
- Make a realistic revision timetable and start early.
- Active recall and spaced repetition beat rereading and highlighting.
- Practise with past papers under timed conditions.
- Sleep, food and breaks support memory and concentration.
- Nerves are normal, and simple strategies can help.
Step 1: know what to expect
Find out the exam format, topics, marks, timing and any rules about calculators or notes. Ask your teacher for a syllabus or past papers. Knowing what is assessed helps you focus on what matters.
Step 2: build a timetable
Work backward from the exam date. List topics and estimate how long each needs, giving more time to weaker areas. Divide your days into short sessions of 25 to 50 minutes with breaks, and include rest days. Keep the plan flexible so that a missed session does not derail everything.
Step 3: study actively
Research on learning, summarised by cognitive psychologists, suggests that two strategies are especially effective:
- Active recall: testing yourself instead of just rereading. Close the book and write down what you remember, use flashcards or answer questions.
- Spaced practice: revisiting material over increasing intervals instead of cramming it all at once.
Rereading and highlighting feel productive but are generally less effective on their own. Mixing topics during practice, known as interleaving, can also help you tell problems apart.
Step 4: use past papers
Practise questions under realistic conditions, with a timer. Afterward, check your answers against mark schemes, find patterns in your errors and revisit those topics. Practice also builds familiarity and reduces anxiety.
Step 5: understand, not just memorise
Explain concepts in your own words, draw diagrams and connect new ideas to what you know. Teaching a friend can reveal gaps. For subjects like maths, work through problems yourself instead of only reading solutions.
Step 6: look after yourself
Sleep helps the brain consolidate learning, so staying up all night is usually counterproductive. Eat regular meals, drink water and include some physical activity. Short breaks, a walk or time with friends reduce stress and help you return to study fresher.
Step 7: the final days
Review summary sheets and weak areas. Prepare what you need the night before, such as ID, pens and a calculator, and know the route and time. Avoid last-minute cramming of entirely new material.
In the exam room
Read instructions carefully, plan your time and answer the questions you know first if the format allows. Keep an eye on the clock. If you feel panicky, pause, take a few slow breaths and refocus on the next question.
Managing stress
Some nervousness can sharpen focus, but persistent worry is harder. Talking to friends, teachers or family helps. If anxiety is overwhelming or affects your daily life, talk to a school counsellor or healthcare professional.
Know the format and the mark scheme
Good preparation starts with understanding what examiners want. Check how long the exam is, how many questions there are and how marks are shared out. Learn the command words, which signal the type of answer required. Describe asks for what something is like, explain asks for reasons, compare asks for similarities and differences, and evaluate asks you to weigh evidence and reach a judgement. Past mark schemes show how marks are awarded, and reading them helps you see how many distinct points an answer needs. Aim to give what the question asks, not everything you know.
Revision techniques that work
Some methods are particularly effective. Practice testing, such as answering past questions or using flashcards, is strongly supported by research. Spaced practice, returning to topics over weeks, beats cramming. Blurting involves reading a topic, closing the book and writing down everything you remember, then checking what you missed. Explaining ideas to someone else, or aloud to yourself, exposes gaps. Interleaving mixes different topics in one session so you learn to choose the right method. Rereading and highlighting feel comfortable but are usually less efficient when used alone.
The final week
Use the last week to consolidate, not to learn new material in a panic. Review summary sheets, practise timed questions on your weakest topics and redo past mistakes. Keep a regular sleep pattern, eat properly and take short walks. Prepare practical details, such as identification, stationery, calculator batteries and the route to the exam room. Avoid comparing your progress with others, since that tends to increase anxiety.
Exam technique
In the exam, read all instructions and questions carefully. A common rule of thumb is to allow time in proportion to marks, so a ten-mark question deserves more time than a two-mark question. Start with questions you can answer to build confidence, and mark questions you skip so you can return. For essays, spend a few minutes planning the structure. In calculation questions, show your working, because marks are often awarded for method. Leave a few minutes at the end to check for mistakes and unanswered questions.
After the exam
Try not to dissect every answer with friends, because it rarely helps. Rest, and refocus on the next exam. If results are disappointing, remember that they are one data point, and talk to a teacher about options such as resits or alternative routes. Look at feedback to learn what to change. Many successful people took a winding path, and one set of results does not define your future.
Frequently asked questions
How early should I start revising?
As early as practical, often several weeks before for major exams, with small sessions.
Is group study useful?
It can be, if you stay on task and use it to quiz and explain each other.
Does music help?
It varies. Many people concentrate better without lyrics or in silence.
How many hours a day should I revise?
There is no fixed number, and it depends on the course and your timetable. Short, focused sessions with breaks are more effective than long, unfocused ones. Many students aim for a few hours of quality study on school days and a bit more on free days.
Is staying up all night to study a good idea?
Usually not. Sleep helps the brain consolidate memories, and tiredness reduces concentration and recall. A good night's sleep before an exam is generally worth more than extra hours of last-minute cramming.
What should I do if my mind goes blank?
Pause, breathe slowly and move on to a question you can answer. Write down anything related to the topic, because it can trigger memories. Often the answer returns after you have settled and done another question.
