GCSE Mock Exams 2026–27: What to Revise First, Subject by Subject
GCSE mock exams are the first real measure of where Year 11 stands, and in the 2026–27 season most schools are running them between mid-November and late January. The fastest way to waste the next four weeks is to revise everything equally. This guide sets out what to revise first in each subject, based on what mock papers actually test and how much of the specification you will have covered by now.
What should you revise first for GCSE mocks?
Revise the topics that are both heavily weighted in the exam and already taught. In practice that means number and algebra in maths, the required practicals and core equations in science, and one well-rehearsed text per English Literature paper. Mocks only test what you have been taught, so ask each teacher for the topic list before you plan anything.
That last sentence is the whole method. Everything below assumes you have that list.
What we see on our own learning portal: UK visitors to Tutopiya’s learning portal totalled 4,586 over the 30 days to 5 November 2026, and UK GCSE subject pages were the fastest-growing group on the portal — visitors to Edexcel and AQA GCSE Maths, Biology, Chemistry and Combined Science pages roughly doubled month on month as mock season began. (Tutopiya learning portal data, 30 days to 5 November 2026.)
How are mocks different from the real GCSE?
| Mock exams | Summer GCSE exams | |
|---|---|---|
| Who sets the paper | Your school, usually from a past paper or a board-published practice set | AQA, Pearson Edexcel, OCR or WJEC Eduqas |
| Content covered | Only what has been taught so far | The full specification |
| Grade boundaries | Set by the school, often using last summer’s boundaries | Set nationally after all scripts are marked |
| What the result is used for | Predicted grades, tier entry, intervention, setting | Your certificated GCSE grade |
| Access arrangements | Usually trialled here first | Formally applied under JCQ rules |
The most useful consequence of that table: because mocks cover less content, the same number of marks is spread over fewer topics. Each topic is worth more in a mock than it will be in June.
Maths: start with number and algebra, not the hardest topics
AQA, Edexcel and OCR all weight number, algebra, and ratio and proportion heavily at both tiers. At Foundation, number alone is 22–28 percent of the paper. At Higher, algebra is 30 percent. Those are the marks that decide grades.
Revise in this order:
- Fractions, percentages, ratio and proportion — these appear in every paper and in disguised form inside science questions too.
- Solving equations and rearranging formulae — the single most transferable algebra skill.
- Standard form, indices and surds (Higher) or place value and rounding (Foundation).
- Angles, Pythagoras and trigonometry — high-frequency geometry.
- Probability and statistics diagrams — quick marks that students routinely drop.
Leave circle theorems, vectors, iteration and histograms until last unless your teacher says they are on the paper. They are worth fewer marks and cost more hours.
Work through questions by topic rather than whole papers. Whole papers are for the final week, when you need to practise pacing.
Science: required practicals and equations come first
Combined Science and the separate sciences both give a large and predictable share of marks to practical work and to the equations you are expected to recall.
- Biology: required practicals, enzymes, transport in plants and animals, and the nervous and endocrine systems. Learn the standard experimental method for each practical — variables, control, and the one thing that makes the result unreliable.
- Chemistry: the mole and reacting masses calculations, electrolysis, rates of reaction, and the required practicals. Calculation marks are the biggest single differentiator at grades 6 to 9.
- Physics: the equations. Students taking exams in 2027 are supplied with an equation sheet for physics and combined science, but it does not cover everything and it is no use if you cannot select and rearrange the right equation. We cover exactly what is and is not provided in GCSE Maths and Physics formula sheets 2027.
If you are sitting Edexcel Combined Science and want to move from a 5-5 to a 7-7, the marks sit in a narrow band of skills — see Edexcel GCSE Combined Science: how to move from a 5-5 to a 7-7.
AQA Biology students should start with the required practical list, which is published and finite: AQA GCSE Biology required practicals.
English Language: technique, not content
There is nothing to learn for English Language — the texts are unseen. What you revise is a process:
- A fixed reading order for each question (read the question, scan for the lines it names, annotate, then write).
- A timing plan per question, written on the front of your paper in the first minute.
- Three or four sentence openers for analysis that you can deploy without thinking.
- The writing question structure. This is the single biggest block of marks in Paper 1 and Paper 2 and the one most students under-prepare.
Write two full practice responses under timed conditions. That is worth more than ten annotated extracts.
English Literature: one text per paper, properly
Literature is closed-book for most boards, so you need quotations in memory. Do not try to revise every text equally. Pick the text on each paper you know best and make it exam-ready:
- 12 to 15 short quotations, chosen because they can be used for several themes.
- Three themes you can write about for any question.
- Two paragraphs of context you can adapt.
Then give the remaining texts a lighter pass. A secure grade 6 on a text you know beats two half-remembered grade 4s.
Humanities and languages
History and Geography: revise the case studies and named examples first. Most lost marks in both subjects come from answers that are correct in general but contain no specific example. Make a one-page list of every named case study with three facts each.
Modern languages: vocabulary for the themes already taught, plus the three tenses you need to hit the higher bands. Speaking mock preparation should be spoken out loud, not read.
A four-week mock plan that works
- Week 1 — audit. Get the topic list from every teacher. Write each topic on a line and RAG-rate it (red, amber, green). Revise nothing yet.
- Week 2 — reds. Work only on red topics, using worked examples then questions. Convert as many as possible to amber.
- Week 3 — questions. Topic-by-topic past-paper questions, marked against the official mark scheme. Keep an error log.
- Week 4 — full papers and the error log. One full paper per examined subject under time, plus a second pass at everything in the error log.
The error log is the part students skip and the part that moves grades. A question you got wrong and never revisited is a question you will get wrong again in June.
After the mocks: the bit that matters more than the revision
Mock papers are the most detailed feedback you will get before the real thing, and most students read the grade and file the paper. Going through the script properly — question by question, against the mark scheme — is worth more than another week of revision. Our guide on how to review GCSE mock papers properly sets out the process, and how to revise for GCSE mocks without wasting time covers the habits to drop.
Sources and a caveat
Mock exams are set and timetabled by individual schools, so there is no national mock timetable from AQA, Pearson Edexcel, OCR or JCQ. Specification weightings referenced here come from the current GCSE specifications published by AQA, Pearson Edexcel and OCR. Your teachers’ topic lists override everything in this article.

Next step: pick the one subject you are least confident in and book a diagnostic session with a specialist GCSE tutor — find a GCSE maths or science tutor and start with a past-paper walkthrough rather than a content recap.
Frequently asked questions
When are GCSE mock exams in 2026-27? +
Most English schools run Year 11 GCSE mocks between mid-November and the end of January, with a second set in February or March for some subjects. Mocks are set by the school, not by AQA, Edexcel or OCR, so your school's internal calendar is the only reliable date source.
Do GCSE mock results matter? +
They matter for three practical things: your predicted grades, your set or tier entry (foundation versus higher), and the evidence your school would use if exams were ever disrupted. They do not form part of your final GCSE grade in a normal year.
How long should I revise for GCSE mocks? +
Six to eight hours a week across the four weeks before mocks is realistic alongside homework. Quality matters more than hours: one hour of answering past-paper questions under time beats three hours of re-reading notes.
Should I revise everything for mocks? +
No. Mocks usually cover only what you have been taught so far, which is typically 60 to 80 percent of the specification. Ask each teacher exactly which topics are examinable and revise only those.
What is the best way to revise for GCSE maths mocks? +
Work through past-paper questions by topic, mark them with the official mark scheme, and keep a list of every question type you got wrong. Re-attempt that list a week later. Topic-by-topic past papers beat full papers until the final week.
How many UK students use Tutopiya's GCSE revision resources? +
The United Kingdom sent 4,586 unique visitors to Tutopiya's learning portal in the 30 days to 5 November 2026, and UK GCSE subject pages were the fastest-growing group on the portal, with Edexcel and AQA GCSE Maths, Biology, Chemistry and Combined Science visitors roughly doubling month on month as mock season began. Figures come from Tutopiya's own learning portal analytics, read from the Learning Portal growth and health dashboard on 6 November 2026.
