Overview
In May 2026, Cambridge International confirmed that several live papers were leaked before or during the exam window. The board's response — voiding affected components and awarding assessed marks instead — is now one of the most searched questions on student forums, WhatsApp groups, and Reddit threads worldwide.
If your physics, maths, or computer science component was impacted, you are not alone — and you are not powerless. Here is how assessed marks actually work, what Cambridge has announced, and how to protect the rest of your grade.
Quick answer
For Cambridge Cambridge exams 2026, > Key takeaway: Assessed marks are Cambridge's standard fairness tool when a component cannot be used. They are not a punishment — but they also are not something you can game. Focus on the papers you will sit.
| Question | Answer |
|---|---|
| What is an assessed mark? | A calculated mark for a component you did not sit (or whose paper was voided), based on your performance on other components in the same syllabus |
| Do assessed marks hurt my grade? | Cambridge says the method places you in the same relative position as on the papers you did sit — no systematic advantage or disadvantage |
| Will results still come on 11 August 2026? | Yes — Cambridge has confirmed the June 2026 results day is unchanged |
| Should I stop revising other papers? | No — every remaining component still counts fully; strong marks there strengthen your assessed-mark profile |
What happened in May 2026 (confirmed news)
For Cambridge Cambridge exams 2026, major outlets including the [BBC reported in late May 2026](https://www.bbc.com/news/articles/cqxpp7er5pzo) that Cambridge voided papers after leaks circulated online. Confirmed developments include:
| Subject / component | What Cambridge did |
|---|---|
| A-Level Physics (papers sat ~20 May) | Component voided; assessed marks for affected candidates |
| AS/A-Level Mathematics 9709 (multiple components, zones 3 & 4) | Some papers voided or postponed; replacement sittings scheduled (e.g. Paper 32 re-sit 8 June 2026, Paper 12 retake 9 June 2026 in affected regions) |
| AS Computer Science 9618/12 (Pakistan) | Paper shared prematurely; assessed marks for all candidates in Pakistan |
| Upcoming physics papers | Replaced as a precautionary step where needed |
Cambridge also warned that many social-media "leaks" are fake — designed to exploit exam stress or sell access.

How Cambridge calculates assessed marks
For Cambridge Cambridge exams 2026, when a component cannot be used to award a grade, Cambridge does not leave a hole in your certificate. Instead, senior assessment experts apply a well-established statistical method:
- Take the marks you earned on the other components you sat in that syllabus entry
- Compare your performance on those components to all candidates worldwide who sat them
- Place you in the same relative position for the missing/voided component as you achieved on the rest
A simple illustration
Imagine a syllabus where Paper 1, Paper 2, and Paper 3 each count 33%. You sat Paper 1 and Paper 3 strongly — around the 75th percentile globally. Paper 2 was voided. Cambridge awards an assessed mark for Paper 2 that also places you near the 75th percentile for that component, based on the global cohort.
This is why Cambridge states that candidates with assessed marks should have no systematic advantage or disadvantage compared with students who sat every paper normally.
What assessed marks are not
| Myth | Reality |
|---|---|
| "They'll give everyone a C" | Marks follow your profile on other components |
| "Assessed marks are always lower" | Not systematically — they mirror relative performance |
| "I can ignore my remaining exams" | Other components still count at full weight |
| "Looking at a leak won't matter" | Malpractice investigations continue separately — see integrity guide |
Replacement exams vs assessed marks
For Cambridge Cambridge exams 2026, cambridge uses two different tools depending on timing and security:
| Situation | Typical response |
|---|---|
| Paper leaked before the sitting (candidates had not yet taken it) | New paper sat on a rescheduled date |
| Paper sat but later voided due to breach | Assessed mark for that component |
| Paper postponed pending investigation | Replacement sitting announced to schools |
9709 Mathematics — what students in zones 3 & 4 should know
If you are registered for 9709 in affected administrative zones:
- Paper 32 (A-Level) — replacement exam scheduled Monday 8 June 2026 (per Cambridge school communications reported in regional press)
- Paper 12 (AS) — new version of the exam Tuesday 9 June 2026 for candidates in affected regions
- Paper 52 — assessed marks for all candidates in zones 3 and 4
- Withdrawal / carry-forward — Cambridge extended withdrawal deadlines and, in some cases, the 13-month carry-forward rule for students unable to sit the replacement paper
See our dedicated 9709 maths resit June 2026 guide for component codes, withdrawal options, and revision focus.
What you should do right now
For Cambridge Cambridge exams 2026, cambridge briefs exams officers, not TikTok. Your centre will tell you:
1. Check official school communications only
- Whether you are on assessed marks, a replacement paper, or unaffected
- Venue, timing, and entry/withdrawal deadlines
2. Maximise marks on every remaining component
Assessed marks pull from your other papers. A strong Paper 4 or coursework component directly supports a fair calculated mark elsewhere.
| Action | Why |
|---|---|
| Timed past paper on remaining components | Builds exam fitness |
| Strict mark-scheme marking | Finds repeatable errors |
| Examiner report for your syllabus code | Shows what lost marks that series |
Use 9709 past papers or your subject hub — then mark your answers against the real scheme.
3. Do not chase "replacement paper leaks"
Replacement sittings use new confidential papers. Any file claiming to be the June 8 or June 9 paper is either fake or malpractice. Report it to your exams officer.
4. Document your own integrity
If group chats shared suspicious material:
- Do not forward or save files
- Tell your exams officer when you received content and that you did not use it
- Keep revising with published past papers only
Assessed marks and university offers
For Cambridge Cambridge exams 2026, cambridge has stated that June 2026 grades will release on schedule (11 August 2026) so university offer deadlines are met. Assessed marks appear on your results statement like any other component mark — universities are familiar with this process from prior breach years.
If you are applying through UCAS or international equivalents, your centre can confirm how Cambridge reports voided components on statements of results.
How this differs from IB grade boundaries
For Cambridge Cambridge exams 2026, cambridge assessed marks solve a missing component problem after a security breach. IB grade boundaries solve a difficulty calibration problem after marking — converting raw marks to 1–7. Different systems, different triggers. IB students should read [IB grade boundaries explained](/blog/ib-grade-boundaries-explained) instead.
FAQ
For Cambridge Cambridge exams 2026, your exams officer may know which components are affected before results release. The final certificate shows component marks without always labelling them "assessed" to students — ask your centre if you need confirmation for university forms.
Will I know I got an assessed mark before results day?
Can I appeal an assessed mark?
Standard enquiry about results processes apply. Grounds usually require evidence of an administrative error, not disagreement with the statistical method itself.
What if I missed another component through illness?
Assessed marks for leaks are different from special consideration. Illness exemptions follow Cambridge's separate procedures — speak to your exams officer immediately.
Does this affect O-Level and IGCSE students?
The May 2026 news cycle focused on international A-Level and AS-Level breaches in specific zones. IGCSE integrity rules are the same in principle — your school communicates any centre-specific actions.
Are digital exams safer from leaks?
Digital rollout continues separately — see Cambridge digital exams June 2026. Security breaches can affect any delivery mode; preparation stays the same: official past papers and honest marking.
