Starting revision can feel surprisingly difficult. You may know that exams are approaching, but deciding what to revise first, how long to spend and which revision method to use can quickly become overwhelming.

The good news is that you do not need a perfect revision timetable, a new set of stationery or six free hours to get started. You only need a clear first task.

This guide explains how to start revising for your GCSEs or A-Levels, one manageable step at a time.

What Should You Do When Revision Feels Overwhelming?

When you think about every subject, topic, homework deadline and exam at the same time, revision can feel impossible.

The solution is not to work harder immediately. It is to make the task smaller.

Instead of telling yourself:

“I need to revise all of biology.”

Choose something more specific:

“I am going to test myself on cell structure for 20 minutes.”

A clear, limited task feels much easier to begin than a vague goal such as “revise science”.

When revision feels overwhelming:

Write down everything you think you need to revise.
Divide large subjects into smaller topics.
Choose one manageable topic.
Decide exactly what you will do during the session.
Start with a short amount of time.

You do not have to solve your entire revision plan today. Your first goal is simply to complete one useful session.

Make a List of Your Subjects

Begin by writing down every subject you are studying.

A GCSE student might list:

English Language
English Literature
Maths
Biology
Chemistry
Physics
History
French

An A-Level student may have fewer subjects, but each one will contain a much larger amount of content.

Do not rely on memory when making your list. Check your school timetable, online learning platform or exam entries to make sure nothing is missing.

Once you have listed your subjects, leave space underneath each one for its individual topics.

This transforms revision from one enormous task into a collection of smaller, more manageable tasks.

Break Each Subject into Topics

Writing “revise psychology” or “revise maths” on a timetable is rarely helpful. These tasks are too broad, which makes it difficult to know where to begin or recognise when you have finished.

Instead, divide each subject into specific topics.

For example, A-Level Psychology could be divided into:

Social influence
Memory
Attachment
Psychopathology
Approaches in psychology
Biopsychology
Research methods
Issues and debates

A GCSE Chemistry list might include:

Atomic structure
Bonding
Quantitative chemistry
Chemical changes
Energy changes
Rates of reaction
Organic chemistry
Chemical analysis
Chemistry of the atmosphere
Using resources

You can then break larger topics into smaller sections if necessary.

For example, “memory” could be divided into:

The multi-store model
Types of long-term memory
The working memory model
Interference
Retrieval failure
Eyewitness testimony

The more specific your topic list is, the easier it becomes to plan focused revision sessions.

Use the Specification or Course Checklist

One of the best ways to make an accurate revision list is to use the specification for your course.

The specification is the official document produced by the exam board. It explains the content and skills that can be assessed in your exams.

Your school may also provide a simpler course checklist based on the specification.

Using the specification helps you avoid two common problems:

Missing topics that could appear in the exam
Spending time revising material that is not part of your course

Make sure you are using the correct:

Subject
Qualification level
Exam board
Specification
Course year

For example, two students studying GCSE History may be learning completely different topics depending on their exam board and the options selected by their school.

Use your course checklist alongside the Complete Guide to Revising for GCSEs and A-Levels [The Complete Guide to Revising for GCSEs and A-Levels] to build a complete picture of what your revision needs to cover.

Your subject hub should also contain exam-board-specific revision notes, topic questions and exam guidance.

Turn the Specification into a Revision Checklist

Create a checklist containing every topic you need to know.

You can do this on paper, in a spreadsheet or using a notes app.

Keep the system simple. You might include columns for:

Topic	Confidence	Revised	Questions completed	Needs reviewing
Atomic structure	High	Yes	Yes	No
Bonding	Medium	Yes	No	Yes
Quantitative chemistry	Low	No	No	Yes

Do not mark a topic as complete simply because you have read your notes. A topic is more securely learned when you can recall the information and use it to answer questions.

Your checklist should be a working document. Update it as your knowledge improves and as you discover new gaps.

Identify Your Strong and Weak Areas

You do not need to spend the same amount of time on every topic.

Some topics will already feel secure, while others may be difficult, unfamiliar or partly forgotten.

A simple traffic-light system can help:

Green: I understand this topic and can answer questions on it.
Amber: I know some of it, but I make mistakes or forget important details.
Red: I do not understand this topic or cannot recall the key content.

Be honest with yourself. A topic should not be green just because you recognise the information when reading your notes.

Ask yourself:

Can I explain this without looking at my notes?
Can I define the key terms?
Can I complete an exam question on it?
Can I apply the content to an unfamiliar example?
Can I remember it several days later?

You can also use:

Previous test results
Mock exam feedback
Teacher comments
Homework marks
Topic quizzes
Practice questions
Past papers
Predicted papers

A full predicted paper is one of the best ways to identify weaknesses once you have reviewed a reasonable amount of the course. It tests whether you can bring together knowledge from different topics under realistic exam conditions.

Read How to Find Your Weakest Topics [How to Find Your Weakest Topics] for a more detailed system.

Do Not Only Revise Your Favourite Topics

It is tempting to begin with the topic you enjoy most. This can help you build momentum, but it can also become a way of avoiding more difficult material.

Students often repeatedly revise topics they already understand because this feels productive and reassuring.

Effective revision should include a balance of:

Weak topics that need significant improvement
Medium-confidence topics that could quickly become strengths
Strong topics that need occasional review

You should spend more time on weak areas, but do not completely ignore stronger topics. Knowledge can fade when it is not revisited.

How Should You Choose the First Topic?

Your first topic should be specific and manageable.

A good first topic is usually:

Small enough to cover in one session
Important for the course
Something you partly understand
Easy to test with questions or self-quizzing

Starting with the most difficult topic on your entire course may leave you feeling discouraged. Starting with the easiest topic may not address your most important gaps.

A medium-difficulty topic is often a good place to begin.

For example:

Not: “Revise GCSE Maths”
Better: “Complete ten expanding-brackets questions”
Not: “Revise A-Level Sociology”
Better: “Recall three explanations of educational achievement”
Not: “Revise English Literature”
Better: “Create a quotation quiz for one character”

Your task should describe an action, not just a subject.

Useful revision actions include:

Answer ten retrieval questions
Complete a brain dump
Make and test ten flashcards
Explain a process without notes
Complete one exam question
Mark and improve an answer
Label a diagram from memory
Plan one essay

The Best Revision Techniques for GCSEs and A-Levels [The Best Revision Techniques for GCSEs and A-Levels] explains which activities are most likely to help you remember and apply what you have learned.

Start with a Manageable Revision Session

Your first revision session does not need to last for hours.

Try starting with 20 to 30 minutes.

A simple first session might look like this:

Five minutes: Choose the exact content

Select one small section of a topic.

For example:

Types of conformity
Simultaneous equations
Rates of reaction
Causes of the First World War

Ten minutes: Review the content

Read a concise set of revision notes, watch a short explanation or look through a worked example.

Do not spend the whole session reading. The aim is to prepare yourself to retrieve or apply the information.

Ten minutes: Test yourself

Close your notes and:

Write down everything you remember
Answer flashcards
Complete a short quiz
Explain the topic aloud
Attempt an exam question

This is known as retrieval practice. Read Retrieval Practice Explained [Retrieval Practice Explained] to learn how to use it effectively.

Five minutes: Check and improve

Compare your answer with your revision notes or mark scheme.

Correct mistakes and write down what needs to be reviewed next time.

At the end of the session, decide on your next small task. This makes it much easier to start again tomorrow.

What Is the Best Way to Revise?

The most effective revision is active.

Active revision requires you to retrieve information, apply knowledge or solve problems. It gives you evidence of what you can actually remember.

Examples include:

Answering questions
Using flashcards
Completing brain dumps
Explaining ideas aloud
Planning essays
Solving calculations
Completing timed exam questions
Marking and improving answers

Passive activities can feel easier, but they do not always lead to secure learning.

Passive revision includes:

Repeatedly rereading notes
Copying paragraphs from a textbook
Highlighting large amounts of text
Watching videos without testing yourself
Looking at completed answers without attempting them

You can still use notes and videos to learn content. However, each revision session should include an opportunity to test what you know.

Use Practice Questions Early

You do not need to know an entire subject before attempting exam questions.

Practice questions can help you:

Understand how topics are assessed
Learn important command words
Apply your knowledge
Identify missing content
Improve the structure of your answers
Become familiar with mark schemes

Start with short topic questions while learning the course. As you become more confident, move on to longer questions and complete papers.

Read Why Practice Questions Are Essential for Revision [Why Practice Questions Are Essential for Revision] for guidance on building exam practice into your revision.

When Should You Complete a Predicted Paper?

A predicted paper should usually come after you have completed some initial topic revision.

It should not be the very first thing you do if you have not reviewed the course content, as a very low score may simply confirm that you have not started revising yet.

A useful revision sequence is:

Use the specification to identify the content.
Review key topics.
Use retrieval practice.
Complete topic-based exam questions.
Attempt a predicted paper under timed conditions.
Mark the paper carefully.
Return to the topics where you lost marks.
Repeat similar questions later.

Our predicted papers are one of the best ways to test your progress because they bring together knowledge from across the course in a realistic exam format.

They can help you distinguish between:

Topics you have not learned
Topics you have forgotten
Questions you have misunderstood
Answers that lack detail
Problems with timing
Weak exam technique

Read How to Use a Predicted Paper to Revise [How to Use a Predicted Paper to Revise] before attempting your first full paper.

Make a Simple Revision Timetable

Once you have created your topic list and identified your weaker areas, you can begin planning future sessions.

Your revision timetable does not need to account for every minute of every day.

A useful timetable should show:

Which subject you will revise
The exact topic
The activity you will complete
How long you will spend
When you will revisit the topic
When you will complete practice papers

Instead of writing:

Monday: Chemistry

Write:

Monday, 5:00 pm: Test myself on ionic, covalent and metallic bonding for 30 minutes.

Specific tasks reduce the amount of decision-making required when it is time to begin.

How Much Revision Should You Do?

There is no perfect number of hours that applies to every GCSE or A-Level student.

The amount of revision you need will depend on:

How close your exams are
How many subjects you study
Your current knowledge
Your target grades
Your school workload
Your personal circumstances
The difficulty of each topic

Consistency matters more than completing an occasional very long session.

Thirty focused minutes repeated regularly is usually more useful than spending several hours copying notes while distracted.

Build up gradually. You may begin with one short session each day and increase the amount as your exams approach.

Read How Much Revision Should You Do Each Day? [How Much Revision Should You Do Each Day?] for more detailed advice.

What If You Keep Putting Revision Off?

Procrastination often happens because the task feels too large, unclear or uncomfortable.

Make starting as easy as possible.

Try this five-minute method:

Put your phone in another room.
Open the exact page or resource you need.
Set a timer for five minutes.
Complete one tiny revision action.
Continue if you feel able.

You might:

Answer one flashcard
Read one page
Complete one calculation
Write one paragraph
List five key terms

Starting is often the hardest part. Once you have begun, continuing usually feels easier.

Your First Revision Session Checklist

Before your first session, check that you have:

Listed your subjects
Found the correct specification or course checklist
Broken one subject into smaller topics
Identified a manageable first topic
Chosen an active revision task
Removed obvious distractions
Set a realistic time limit
Planned how you will test yourself
Left time to check your answers

You do not need to complete every step perfectly. A basic plan that you actually follow is better than an elaborate timetable that you never begin.

Start Revising Today

The best way to start revising is to make one clear decision:

What small, useful revision task can I complete today?

Choose one topic. Set a timer. Review the content briefly, then close your notes and test what you can remember.

Once you have completed that first session, record what went well and choose your next task.

As your revision progresses, use our free revision notes, topic questions and subject-specific revision guides to strengthen your knowledge. When you are ready to test your overall progress, complete one of our GCSE or A-Level predicted papers under timed conditions.

Revision does not need to begin with a perfect plan. It begins with one focused session. 📚
