See Which Topics Your Past Papers Never Touched — Free
Revision by past paper feels like coverage until the exam asks about the one topic that never came up in the three years you practised. This binder takes your topic list and the papers you have actually done, checks each topic against them sheet by sheet, and prints the tabs with nothing behind them — the gaps in your revision, in the order you should close them.
The proof surface
Free path: the binder computes locally in the browser with no key and no account. Where an AI step helps, any free chat assistant works — Google AI Studio's free tier and Groq's free tier were both no-card and rate-limited when this page was reviewed on 2026-09-13 (limits change; check before you rely on them).
Why the flat version breaks
A stack of completed past papers is evidence of effort, not of coverage. Without a topic list beside it, the same three topics get practised every year because they are the ones that come up first. Marking each topic against the papers you have done turns a pile of practice into a map with visible holes.
How to use the revision coverage binder in four passes
Your notes only contain what you have already revised. The specification's topic headings are the rows that matter, including the ones you have avoided all year.
A paper you read but did not attempt is not coverage. Marking it makes the binder optimistic, and an optimistic coverage map is worse than none because it stops you revising the gap.
A topic worth 20 marks that has never appeared is the highest-value revision in the whole plan — it is also the one most likely to be on this year's paper precisely because it has not been on a recent paper.
Each paper you complete changes the marks. Re-run it weekly and watch the boxed rows fall; that count is a better measure of exam readiness than the number of papers done.
SAMPLE DATA, NOT A VERIFIED CLAIM: A-level Biology Paper 3 · exam 12 Jun 2027 · fourteen topics · five papers done · respiration and photosynthesis in every paper · biodiversity and population genetics in none. Replace these values with your own source before you rely on anything.
What breaks first
Marking a topic as covered because it is in your notes
Coverage means a question you answered under time. A topic you have read about and never practised is still a gap, and the binder only records what you tell it.
Treating one appearance as safe
A topic that came up once in five papers can come up twice this year. Rows with a single mark are half-gaps: revise them, just after the empty ones.
Revising the topics you already know because they are on the list
The comfortable rows are the ones with four and five marks against them. They are covered; the binder exists to point you at the sheets that are not.
What you pay otherwise
| The usual route | What it leaves out | Cost |
|---|---|---|
| A revision platform with topic tracking | Tracks the questions it sets you, not the papers you have done | a monthly subscription |
| A tutor's coverage check | Accurate, and scheduled around their availability | an hourly rate |
| Discovering the gap in the exam room | The topic nobody has asked in five years turns up worth 20 marks | a grade and a resit |
| This page + the free revision coverage binder | Computed in your tab, result on screen before you type anything | $0 |

Fourteen biology topics are already marked against five papers, with three sheets boxed as uncovered. Mark one of those gaps against a sixth paper and the boxed count falls to two.
Open the free revision coverage binder →Keep the work if you will use it again
Every topic, the paper key, the coverage marks and the boxed gaps, plus copy and share-link, with no account.
The on-screen result is free and repeatable forever. The one-time tier adds a tangible file you keep and the saved history that comes with it; it never removes or degrades the free result.
Boundary: This records the coverage you mark; it cannot predict an exam, it does not know a syllabus's weighting, and past paper frequency is not a guarantee of what will appear. Work from your own specification and your teacher's guidance, and revise the whole syllabus rather than only the gaps.
