What the December round is, and when
The December round is our second free mock round of 2026-27. Papers open on 7 December and close at the end of 20 December 2026, UK time. Within that window you start each paper when it suits you. There’s no fixed exam slot, and each paper is timed from the moment you start it. The papers are original practice papers written by Revise Right to follow your board’s specification and format. They are not real exam board papers, and AQA, Pearson Edexcel and OCR did not write or endorse them.
Who it’s for
GCSE and A-Level students taking AQA, Edexcel and OCR, in Biology, Chemistry, Physics, Maths and English Language. School mock dates vary a lot. In our check of 46 schools’ published 2026-27 dates, 27 of the 38 with Year 11 dates start their first mocks in November, three in December, four in January and two in February. So for most Year 11s, December comes after school mocks. Use it to redo your weakest subject under timed conditions once you’ve worked on the gaps. If your school mocks are in January or February, it’s a full run-through first.
Year 11 and Year 13 students who want an extra timed paper before the summer.
Students whose school mocks went badly and who want a second go.
Home-educated and private candidates who have no school mocks (see below).
How to sign up
Sign-up is on our mocks page, in the section called “Sit a free mock in December”.
Choose your level (GCSE or A-Level), your subjects and an exam board for each.
If you’re new, create a free account. Your choices are kept on your device while you sign up. Your free 5-day Pro trial starts automatically when you verify your new account. No card or automatic charge.
If you already have an account, log in and your place is saved straight away.
We email you when your papers open on 7 December. You can change your subjects or boards later on the same page.
What you get, and when
During the paper there’s no tutor, no hints and no instant marking, and submitting locks your answers. You can choose exam conditions (the timer keeps running) or flexible practice (you can pause, and the attempt is labelled as practice). About a week after you submit, once marking and checks are done, we email you that your results are ready. Written answers are AI-marked against the mark scheme for each question, and answers with one right answer are checked automatically.
Your score as a percentage.
An estimated grade, worked out from last summer’s grade boundaries. These are original papers, so treat it as an estimate.
The marks you earned and missed on each question.

Revise Right December mocks vs Medly Mocks

Private and home-educated candidates
If you’re home-educated, you sit GCSEs and A-Levels as a private candidate. The Joint Council for Qualifications (JCQ) lists “home-schooled” students among private candidates, and says you are responsible for making your own entries through an exam centre and paying any fees. That usually means no school mocks, so a full timed paper is harder to arrange. Some centres run mocks for their own reasons. Exam Centre London, for example, asks private candidates who want UCAS predicted grades to sit a mock paper under controlled conditions at its centre. Our December mocks don’t need a school. Any student with a free account can sign up and sit them at home. They don’t enter you for exams and they can’t stand in for a centre’s mock for predicted grades, but they are a free way to practise a full timed paper and see which topics to work on.
When we checked Medly’s mocks page on 29 October 2026, it covered Medly Mocks ’26 on 26–31 October 2026, with results on 3 November. It didn’t list a December round. Check medlyai.com for their latest dates.
How are Revise Right’s December mocks different from Medly Mocks?
Ours run 7–20 December 2026 and you start each paper when it suits you in that window. Medly’s October round set one subject per day, each open for 24 hours, with 5,000 free places. Both give an estimated grade, a percentage and a topic breakdown. Medly adds a national ranking and percentile; we don’t rank students. Our results come about a week after you submit.
Which should I sit, Revise Right or Medly?
Whichever fits your dates. If you want a ranking against other students, Medly offers one. If you want a timed paper in December, before or between school mock rounds, ours is open then. They’re both free, so you can sit both. We make Revise Right. Nobody paid to be on this page.
Can home-educated or private candidates sit the December mocks?
Yes. You don’t need a school to sign up. Create a free account, choose your level, subjects and boards on our mocks page, and sit the papers at home. They are practice only: they don’t enter you for exams and they aren’t a centre mock for UCAS predicted grades.
Do these mocks count towards my GCSEs or predicted grades?
No. They are original practice papers, not exam board papers, and the result is an estimate for you. Your school or exam centre sets predicted grades. Use your results to decide what to revise next.
When do results arrive?
About a week after you submit, once marking and checks are done. We email you when they’re ready, and you see them in your Revise Right account: a percentage, an estimated grade and a topic-by-topic breakdown.
