Here is the uncomfortable truth about mocks. They are not a dress rehearsal for the summer. They are a test you sit before your teachers have finished teaching you the course, and the most useful thing they produce is not a grade. It is a list of everything you got wrong.
So learning how to revise for mocks is a slightly different skill from revising for the real thing. You have less content, less time, and higher stakes than most students realise. Mock results feed predicted grades, sixth-form and college decisions, and in some subjects the tier of paper you sit in June. And the hour you spend reviewing your marked paper in January can be worth more than the ten you spent revising in December.
This guide gives you a six-week mock revision plan that starts at October half-term, works around the topics you haven't covered yet, and finishes with the after-mock review almost everyone skips.
What Are Mocks, and Do Mocks Matter?
A mock exam is a practice exam your school sets under real exam conditions, usually using past or specimen papers from your exam board. In England, most Year 11 and Year 13 students sit their mocks between late November and January. Year 12 students usually sit theirs in the summer term.
Mocks carry no official grade. Nobody outside your school ever sees the result on a certificate. But do mocks matter? Yes, for four reasons:
- Predicted grades. Teachers use mock results as one of their main pieces of evidence when they predict your grades for sixth-form, college and UCAS applications.
- Tier and set decisions. In GCSE subjects with foundation and higher papers, such as maths, combined science and languages, mock results often help decide which tier you are entered for.
- Evidence if exams are disrupted. When summer exams were cancelled in 2020 and 2021, schools' own evidence, mock results included, fed into the grades students received.
- It is your best diagnostic. A mock is the only full, timed, marked paper most students sit before the summer. It shows you exactly which topics and which question types cost you marks while there is still time to fix them.
If you want the full summer plan rather than the mock-specific one, the GCSE revision guide and the A-level revision guide cover the whole two-year picture.
Why Revising for Mocks Is Different
Three things make mock revision its own problem.
The course isn't finished. By December you may have covered half or two thirds of the specification. Your mock will only test what you have been taught (ask to be sure), so your revision list is shorter than in May. That is good news. It means a focused plan is realistic.
You're still learning new material. Lessons keep going while you revise. Every week you will be taught something new and still need to hold on to what you learned in September. A plan that stops new learning to revise old topics leaves you behind by January.
The marks are information. A summer exam tells you a grade when it is too late to act on it. A mock tells you something you can still use. That changes what "revising well" means: you want an honest result, not a lucky one.
A mock you crammed for tells you how good your cramming is. A mock you revised for properly tells you what you actually know.
When Should You Start Revising for Mocks?
For most students, four to six weeks of steady revision is enough for GCSE mocks, and six to eight weeks for A-level mocks. If your mocks start in early December, that makes October half-term the natural starting point.
Spread is what matters. One hour a day for six weeks beats six hours a day in the final week. In a review of hundreds of experiments, Cepeda and colleagues (2006) found that spacing study sessions out beats massing them together, and the effect is one of the most reliable findings in learning research.
A realistic weekly load while lessons continue:
| Year | Revision per school day | Weekend | Weekly total |
|---|---|---|---|
| Year 11 (GCSE) | 45 to 60 minutes | 2 to 3 hours | about 6 to 8 hours |
| Year 13 (A-level) | 60 to 90 minutes | 3 to 4 hours | about 8 to 11 hours |
| Final two weeks | Add 30 minutes a day | Add 1 hour | About 2 to 4 hours more |
These are planning figures, not research findings. Adjust them to your school's homework load.
If you need help fitting this around homework, the guide on building a study schedule walks through blocking time week by week, and how to make a revision timetable shows how to turn these six weeks into topic-by-topic sessions.
Your 6-Week Mock Revision Plan
This plan assumes about six weeks between half-term and your first mock. If you have less, compress weeks 2 and 3 into one.
Ask each teacher exactly which topics and papers your mock covers. Then write every topic from the specification on one page per subject and rate each one red (can't do it), amber (shaky) or green (could teach it). This page is your whole plan. Everything after this follows from it.
Spend most of your time on red topics, oldest first, because they have faded the most. For each one, re-learn it from a worked example or your teacher's notes, then turn the facts you need into flashcards: definitions, equations, key quotes, dates. Review those cards a little every day.
Now switch from learning to retrieving. Do past-paper questions on your red and amber topics, mixing several topics in each session instead of doing ten questions on one. Mark every answer against the mark scheme, not against your notes.
Sit at least one full paper per subject under real timing. This is where you find out whether you can finish, and which question types are eating your time. Write down every question you lost marks on.
No new topics this week. Go through your flashcards, redo the questions you got wrong in week 5, and keep a normal bedtime. Sleep across the week before an exam matters more than one extra late-night session.
Why mix topics in week 4? It's called interleaving. In a classic study by Rohrer and Taylor (2007), students who practised mixed maths problems scored far higher on a delayed test than students who practised one problem type at a time. Mixing feels harder. It is also much closer to what the real paper does to you.
And why past papers at all? Because answering questions is itself a way of learning, not just a way of checking. The practice testing guide explains the research in detail.

Two Students, Same Mocks
Here's how the same six weeks can go two different ways.
Maya re-reads her chemistry notes every evening for a fortnight, then crams the weekend before. She gets a grade 5. She looks at the grade, feels disappointed, puts the paper in her bag and never opens it again. In June she loses marks on the same two topics.
The mock told her exactly what to fix. She didn't ask it.
Sam rates every topic, spends four weeks on flashcards and mixed past-paper questions, and sits one timed paper. He also gets a grade 5. Then he sorts every lost mark into a category and finds that 9 of his 22 lost marks came from one topic and 6 came from not reading the question.
He now has two specific things to fix by February. His grade is the same as Maya's. His next six months are not.
The difference isn't effort. It's what each student did with the result.
After the Mock: The Review Worth More Than the Revision
This is the part of mock season that most guides skip, and it's where most of the value is.
When you get your paper back, the natural reaction is to look at the grade and move on. Research suggests the opposite. In a study of word learning, Pashler and colleagues (2005) found that giving the correct answer after a wrong response increased retention a week later by 494%. Feedback after correct answers made little difference. Your wrong answers are where the learning is.
There's a bonus, too. Butterfield and Metcalfe (2001) found that errors people were confident about are more likely to be corrected than wild guesses. This is called the hypercorrection effect. The question you were sure you got right, and didn't, is the one you'll remember once you look at the answer properly.
How to review a marked mock in one hour
- List every question you lost marks on. All of them, including the one-mark slips.
- Sort each one into a category: didn't know it, knew it but misread the question, ran out of time, or knew it but didn't write enough for the marks.
- Count the categories. If most of your lost marks are "didn't know it", you have a content problem. If most are "misread" or "didn't write enough", you have an exam technique problem, and more revision won't fix it.
- Turn every "didn't know it" into flashcards and every technique error into one rule you write at the top of your next practice paper.
- Redo the worst three questions a week later without looking at the mark scheme.
This is sometimes called an exam wrapper: a short reflection on how you prepared and what went wrong, done straight after a test. It takes an hour. It turns a disappointing grade into a plan.
Quick Reference: Mock Revision Situations
| Situation | What to do |
|---|---|
| Mocks are six weeks away | Follow the full six-week plan from week 1 |
| Mocks are two weeks away | Rate topics today, red topics for one week, one timed paper per subject in week two |
| A topic hasn't been taught yet | Ask if it's on the paper; if it is, learn the basics from the textbook and do two exam questions |
| You keep running out of time | Practise timed sections, not full papers, and set a minutes-per-mark target |
| You have mocks in nine subjects | Rotate subjects daily and give the most time to the reddest pages |
| You've just got your results | Do the one-hour review within a week, while the paper is fresh |

Common Mock Revision Mistakes (And How to Fix Them)
Mistake 1: Treating the mock as unimportant
"It's only a mock" is how predicted grades end up lower than they should be.
The fix: Prepare as if it counts, because for sixth-form, college and UCAS decisions it often does.
Mistake 2: Revising topics you haven't been taught
Some students panic and try to learn the whole course in November.
The fix: Ask each teacher what the paper covers. Revise that list and nothing else.
Mistake 3: Making notes instead of testing yourself
Copying and highlighting feel like work. They produce very little memory.
The fix: After you re-learn a topic, close the book and answer questions on it. Dunlosky and colleagues (2013) rated practice testing and spaced practice as the two most useful techniques of the ten they reviewed.
Mistake 4: Never sitting a timed paper
Knowing the content and finishing the paper are different skills.
The fix: Sit at least one full paper per subject under real timing before the mock.
Mistake 5: Letting nerves win on the day
Mock week is often the first time you sit a full set of exams in a hall.
The fix: Treat it as practice for the nerves as well as the content. The guide on handling exam anxiety has techniques you can use the morning of the exam.
Mistake 6: Looking at the grade and nothing else
This is the most expensive mistake on the list.
The fix: Do the one-hour review in the week you get your paper back.
The Research Behind This Plan
- The testing effect (Roediger and Karpicke, 2006): Students who practised retrieving information remembered much more a week later than students who spent the same time re-studying. Read the study.
- Practice testing and distributed practice (Dunlosky, Rawson, Marsh, Nathan and Willingham, 2013): Of ten common techniques, only these two were rated high utility. Re-reading and highlighting were rated low.
- Distributed practice (Cepeda, Pashler, Vul, Wixted and Rohrer, 2006): Across hundreds of experiments, spaced study sessions beat massed ones.
- Interleaved practice (Rohrer and Taylor, 2007): Mixed maths practice produced much better delayed-test scores than practising one problem type at a time.
- Feedback after errors (Pashler, Cepeda, Wixted and Rohrer, 2005): Giving the correct answer after a mistake raised retention a week later by 494%; feedback after correct answers did little.
- The hypercorrection effect (Butterfield and Metcalfe, 2001): Errors made with high confidence are more likely to be corrected after feedback than low-confidence guesses.
Frequently Asked Questions
When should I start revising for mocks?
Start four to six weeks before GCSE mocks and six to eight weeks before A-level mocks. For most schools that means October half-term. Aim for 45 to 90 minutes on school days rather than long weekend sessions, because spreading the same hours over several weeks is remembered far longer than cramming.
Do mocks actually matter?
Yes. Mocks carry no official grade, but teachers use them for predicted grades, sixth-form and college applications and, in some GCSE subjects, deciding whether you sit foundation or higher papers. They are also the best way to find out which topics and question types are costing you marks before the summer.
How do I revise for mocks in one week?
Spend the first evening rating every topic red, amber or green. Use the next four days on your red topics, re-learning each one and then answering exam questions on it. Sit one timed paper per subject in the final two days, review your flashcards, and keep a normal bedtime before each exam.
What if my mock includes topics we haven't covered?
Ask your teacher first, because many schools only examine what has been taught. If an untaught topic is on the paper, learn the basics from your textbook or revision guide and practise two or three exam questions on it. Don't let it take time away from topics you can secure.
What should I do after my mocks?
Within a week of getting your paper back, list every question you lost marks on and sort each one by cause: missing knowledge, misreading, timing or not writing enough. Turn knowledge gaps into flashcards, write one rule for each technique error, and redo your worst three questions a week later.
