Papers written by people who've actually sat them
RealtimeMocks started in an Oxford dorm room — built by a CS student who wanted mock papers that felt like the real thing, not recycled PDFs from 2019. Every question is designed, reviewed, and rubric-scored by students from Oxford and other top universities.

Why we built this
From an Oxford CS student's frustration
I kept downloading “mock papers” that were either too easy, off-spec, or had no way to know how I compared to anyone else. And none of them replicated the pressure of a timed hall sitting.
So I built RealtimeMocks: real timed sittings, paper you write on by hand, AI feedback that actually references the mark scheme, and a cohort rank so you know where you stand. The papers are designed by me and other Oxford students who obsess over getting the difficulty right.

Our process
How a paper gets made
No copy-paste from past papers. Every mock goes through a four-stage pipeline before it reaches the exam hall.
01
Spec the paper
We start from the real exam board specification — topic weightings, mark schemes, and the kinds of questions that actually appear on the day.
02
Write & stress-test
Questions are drafted by subject specialists, then worked through under timed conditions. If we can't solve it cleanly in the allotted time, it doesn't ship.
03
Peer review
Every paper is reviewed by a second pair of eyes — checking difficulty calibration, ambiguity, and whether the marks add up.
04
Build the rubric
Detailed mark schemes and model answers feed into our AI grading pipeline, so feedback mirrors what an examiner would look for.
We sat these exams recently
Not a decade ago. The spec changes, the question styles shift, and we keep up because many of us are still in the system.
Difficulty is intentional
We calibrate each paper against past papers and examiner reports — aiming for 'stretching but fair', not gotcha questions for the sake of it.
Feedback should teach
Marks alone aren't enough. Every rubric is written so the AI can explain what you did well and where your method broke down.
Student voices
What sitters are saying
“The pure paper felt genuinely harder than my school mocks but in a useful way — the last question on integration actually made me rethink my approach. Cohort rank was the wake-up call I needed.”

Pure Paper 1
“Sitting at the same time as hundreds of other people made it feel real. The AI feedback on my working was surprisingly specific — it caught where I'd dropped a factor of 2.”

Mechanics mock
“I liked that it wasn't just a PDF download. The timed upload phase forced me to practice checking my work under pressure, which is exactly what I mess up in real exams.”
Amelia R.
A-level Maths · Year 12
Statistics mock
“Question difficulty was well-tiered — accessible start, brutal finish. Official grade boundaries at the end gave me a much clearer picture than my teacher's vague 'that was a B paper'.”

FM Paper 2
“Did two mocks before my resit. Knowing the papers were written by people who actually understand the spec — not random internet PDFs — made me trust the grade I got back.”

Mixed paper
“The prep phase with the question stems on screen while I had blank paper felt exactly like my centre's arrangement. Small detail, but it mattered.”

Frequently asked
Everything you might want to know before registering for your first sitting.
Every paper is written and reviewed by students and graduates from top universities — including Oxford, Cambridge, and Imperial — who've recently sat or taught the same specifications. We're not a content farm; we're people who've done these exams and remember what tripped us up.
No. RealtimeMocks is an independent platform. Some of our paper designers study at Oxford (and other universities), but we are not endorsed by or connected to the University of Oxford or any exam board.
After you upload photos of your completed script, our system uses vision AI guided by detailed rubrics written alongside each question. You get per-question marks and feedback within minutes. Scripts flagged as unclear may be marked for human review.
On paper — deliberately. You see the questions on screen during the exam phase, work on blank paper as you would in a real hall, then photograph and upload your script. We believe the physical act of writing under time pressure is what most online mocks get wrong.
When the exam window closes, we calculate grade boundaries from the cohort's scores and assign you a rank and percentile. This gives you a realistic sense of where you stand nationally — not just against your classmates.
Pay-per-mock lets you register for individual sittings. Pro gives you unlimited access to all published mocks for the duration of your subscription — ideal if you're preparing across multiple subjects or want to sit several papers before the real thing.
Per-question AI feedback arrives shortly after you upload. Official grades, cohort rank, and percentile are released once the sitting window closes and results are processed — usually within a few hours.
We're exploring school partnerships. If you're a teacher interested in running a cohort sitting for your class, get in touch — we'd love to hear from you.
Independent platform, university-calibre papers
RealtimeMocks is not affiliated with the University of Oxford, Cambridge, or any exam board. Our designers happen to study at these institutions — that's where the rigour comes from, not a logo on the front cover.
