Cambridge IGCSE Remarking, Rechecking and Appeals: the 2026 Rules and Dates
Cambridge's enquiries deadline is 20 September 2026 and the November retake deadline is 21 September — here is what each service can and cannot do.
TL;DR
Cambridge offers four post-results services to individual IGCSE candidates: a clerical re-check (Service 1), a review of marking (Service 2), and versions of each that return a copy of your script. A review of marking is not available for multiple-choice papers — which means Paper 1 or Paper 2 in Biology 0610 and Chemistry 0620, worth 30% of your grade, can only be re-added, never re-marked. Your component mark and percentage uniform mark can go up, stay the same or go down, but your syllabus grade will either stay the same or go up. For the June 2026 series the enquiries deadline is 20 September 2026, and the October/November retake entry deadline is 21 September 2026 — one day later, which is the trap this article exists to explain.

If you are weighing all three routes against each other rather than looking up the regulations, start with the recheck, remark or retake decision guide, which covers Pearson Edexcel alongside Cambridge. This page is the Cambridge rulebook.
What post-results services does Cambridge offer for IGCSE?
Cambridge offers four post-results services for an individual candidate: Service 1(clerical re-check), Service 1S(clerical re-check with a copy of the script), Service 2(review of marking) and Service 2S(review of marking with a copy of the script). A review of marking includes the clerical checks, so you never need both.
The distinction matters more than most people realise. A clerical re-check asks a simple administrative question: was every part of the script marked, and were the marks added up and recorded correctly? Nobody looks at whether the marks themselves were right. A review of marking is the one that puts your script in front of a reviewing examiner to check the mark scheme was applied properly, and it is the only service that can move a mark on a judgement point.
| Service | What Cambridge does | Copy of script | Available on Papers 1 and 2 (multiple choice) |
|---|---|---|---|
| Service 1 | Checks all parts were marked and totals recorded correctly. No marking reviewed. | No | Yes |
| Service 1S | Same as Service 1, plus a copy of the script. | Yes | Yes |
| Service 2 | A reviewing examiner checks the mark scheme was applied correctly. Includes Service 1 checks. | No | No |
| Service 2S | Same as Service 2, plus a copy of the script. | Yes | No |
Three rules from the Cambridge enquiries about results guide for international centres catch families out every August. First, only your school can submit — Cambridge does not accept requests from candidates or parents. Second, all the components you want reviewed in one syllabus must go in at the same time; you cannot add another paper later. Third, the fee is not charged if the enquiry changes your syllabus grade, so a successful enquiry costs nothing.
Cambridge normally issues the outcome within 30 days of receiving the enquiry. Your school gets an acknowledgement letter first, then an outcome letter, both through Direct. If you change your mind, there is a 24-hour window from acknowledgement to amend or cancel without an administration fee.
You cannot get a remark on Biology or Chemistry Paper 1 or 2
Cambridge does not offer a review of marking on multiple-choice question papers. For a Cambridge IGCSE science candidate that removes 30% of the qualification from the remark process entirely — you can ask for a clerical re-check, and nothing more.
This is the single most important restriction in the whole system for our subjects, and almost no results-day guide mentions it. Look at how the papers are built. The Cambridge IGCSE Chemistry 0620 syllabus for 2026 to 2028 sets Paper 1 (Core) and Paper 2 (Extended) as 45-minute papers of 40 four-option multiple-choice questions, each worth 40 marks and 30% of the qualification. Biology 0610 is built identically. So if your disappointment sits in the multiple-choice paper, there is no examiner judgement to review — an answer was right or it was wrong, and only the addition can be checked.
There is one useful consequence of this that helps rather than hurts. Normally you must pick a single service type per syllabus. Cambridge makes an explicit exception for syllabuses that include multiple-choice components, which means a 0620 candidate can request a clerical re-check on Paper 2 and a review of marking on Paper 4 in the same submission. Ask your exams officer to do exactly that if you are unsure where the marks went.
In practice, the paper worth reviewing is nearly always the theory paper. That is where extended-response marks live, where mark schemes require judgement, and where — across more than 20 years of teaching, including 16 years teaching to Cambridge and Edexcel mark schemes at A-level — I have seen the real variation sit.
Can your Cambridge IGCSE mark go down after a remark?
Yes — your component mark and percentage uniform mark can go down. Your syllabus grade cannot. Cambridge's 2026 Handbook says that the syllabus grade will either stay the same or go up after an enquiry, even if a component mark falls. A lower component mark can still matter if it is carried forward to a later series, because Cambridge will use the reduced mark in that later calculation.
That is not a reason to avoid a review that is well justified. It is a reason to understand which number may change. Your current syllabus grade is protected from falling, but the component mark and percentage uniform mark may move in either direction. As the next section explains, a candidate close to a grade boundary may also have had the script checked already.
The mechanism is worth understanding because it explains the outcome letters that frustrate families most: the ones where the reviewing examiner clearly gave a different mark, and the grade did not move.
Why most remarks change nothing: Cambridge's tolerance rule
A mark only changes after a review of marking for one of three reasons: a clerical error in the total, an objective error that is not open to debate, or a difference of professional judgement that is bigger than the tolerance set for that paper. Anything smaller is treated as legitimate variation between two trained examiners, and the original mark stands.
Cambridge's factsheet on how marks on scripts are decided sets out the reasoning. Some marking is objective — a multiple-choice answer is right or wrong, and an objective error is always corrected. But marking a six-mark explanation question requires judgement, and two standardised examiners can legitimately land a mark apart without either being wrong. The acceptable range is called the tolerance, and it is set individually for each paper based on how much judgement that paper demands. Cambridge applies the same tolerance before and after results are published, so that a candidate who pays for an enquiry is not held to a softer standard than one who does not.
Here is the part that changes the decision for most families. Cambridge already runs a grade review before results are released: senior examiners re-mark the scripts of candidates who sit close to a grade threshold and are flagged at risk for at least one other reason. So the classic "I was one mark off an A" case is often a script that has already been through a second pair of eyes. A paid review of marking is a third look under exactly the same tolerance rule.
None of this makes an enquiry pointless. It makes the choice of paper matter. Before you spend anything, work out where the marks went — that is what our classified solved past papers are built for, question type by question type, so you can see whether your weakness was recall, application or practical interpretation.
Read the script before you pay: the free Access to Scripts window
Where Cambridge's Access to Scripts service is available, your school can download your marked script free of charge, and for the June 2026 series the window closes on 4 October 2026. Cambridge currently offers the service only in selected countries, and it is not available to candidates graded through the portfolio-of-evidence route. Its guidance says the service exists partly to help centres decide whether to apply for an enquiry, and which type.
This is the most underused thing on this page. A downloaded script shows the marks each examiner gave at each stage of the process, and annotations in different colours for each stage — original marking, examiner monitoring, grade review, and any enquiry. If you can see that your script already went through grade review, you know a senior examiner has looked at it. If you can see a theory question where a well-developed answer scored nothing, that is a concrete case for a Service 2.
One caution from the same factsheet: the mark on the front of the script may not be your final mark. Examiner scaling, component weighting factors and special consideration adjustments are all applied afterwards and do not appear there. Do not panic-diagnose an error from a number that was never meant to be the final figure.
The June 2026 key dates for international centres put results release on 18 August 2026, the enquiries deadline on 20 September, and the Access to Scripts cut-off on 4 October — which means the free script download stays open for two weeks after the enquiry deadline has closed. Ask your exams officer for the script in the last week of August, not October.
What a Cambridge appeal really investigates
A Cambridge appeal is not a second remark. It asks whether Cambridge followed its own Code of Practice and applied its procedures properly and fairly. Your work is only re-reviewed if the investigation finds a procedural failure that may have affected your mark.
Cambridge's guidance on appealing an enquiry about results is unusually blunt on this point, and the appeals form is blunter still. Three things do not, on their own, count as evidence for an appeal:
- you disagree with the examiner's or moderator's judgement, whether originally or at the enquiry stage
- you disagree with where Cambridge set the grade thresholds
- your result in this subject is out of line with your results in others
Every one of those is a reasonable human feeling. None of them is a ground of appeal. The appeal route exists for the case where something in the process went wrong — not for the case where you believe the mark is too low.
The process runs in two stages, both submitted by your school and supported by the Head of Centre, and both governed by section 7 of the Cambridge Handbook, which sits in the Cambridge exams officers guide. A Stage 1 appeal must be submitted within 28 days of the date Cambridge tells your school the enquiry outcome. If Stage 1 is not fully successful, a Stage 2 appeal must follow within 14 days of the Stage 1 outcome letter, and is heard by an independent panel. Up to three centre staff may attend a Stage 2 hearing, remotely if needed; legal representatives may not.
The 20 versus 21 September problem
The enquiries deadline for June 2026 is 20 September and the November 2026 retake entry deadline is 21 September — but an enquiry outcome takes up to 30 days. In plain terms: if you submit an enquiry in September, you will almost certainly have to decide about the retake before you know whether the enquiry worked.
Look at the calendar as a family experiences it. Results land on 18 August. You spend a week deciding. Your school submits an enquiry in early September. The outcome is due within 30 days, so early October. The retake entry closed on 21 September. If you waited for the outcome, the retake window has shut behind you and you are into very late entry fees, if Cambridge accepts the entry at all.
The way out is to plan for both. Enter the retake before 21 September, prepare as though you are sitting it, and withdraw or simply set it aside if the enquiry goes your way. An unused entry costs a fee. A missed series costs eight months. If your retake needs access arrangements, note that the deadline for those on June 2026 retake entries is earlier still — 10 September 2026.
Retaking Cambridge IGCSE in the October/November 2026 series
Retake entries from the June 2026 series close on 21 September 2026, exams run from late September to mid-November, and results are scheduled for mid-January 2027. Cambridge places no cap on how many times you may sit the qualification: the syllabus states that candidates can retake the whole qualification as many times as they want to.
The November 2026 key dates for international centres set out the rest of the schedule. First-time entries closed on 16 August. The 21 September date is specifically for candidates carrying a June 2026 result forward, which is why it sits after results day rather than before it. Forecast grades are due by 31 October. If you need an enquiry on your November result, that deadline is 26 February 2027, with Access to Scripts closing on 12 March 2027.
Whether November is offered for your syllabus depends on your administrative zone, so confirm with your exams officer before you plan around it.
The teaching problem in a November retake is not content coverage — you have already seen the whole syllabus. It is that you have roughly five weeks between entry and your first paper, and the marks you lost in June were mostly lost in the same three places: imprecise definitions, unexplained calculations, and practical questions answered from memory rather than from the data on the page. That is what our October 2026 IGCSE Biology revision programme and October 2026 IGCSE Chemistry revision programme are built around: examiner-report-driven correction of the specific mark-losing habits, rather than a second pass through the textbook.
If you would rather work through it independently, the IGCSE Biology and Chemistry notes are updated against the current mark schemes and examiner reports each series. Across eight published science textbooks, with more than 20,000 copies sold worldwide, the pattern in the reports has stayed remarkably stable — which is precisely why a targeted retake works.
If you are unsure whether to enter, message us on WhatsApp at +965 5137 5709 or email admin@chem-bio.info before 21 September and we will talk it through with you plainly, including the times the answer is no.
Frequently asked questions
How much does a Cambridge IGCSE remark cost? Fees are set by Cambridge and published to schools through Direct, so your exams officer is the only reliable source for the current figure. The fee is not charged if the enquiry results in a change to your syllabus grade.
Can I apply for a remark myself without my school? No. Cambridge only accepts enquiries about results submitted by the centre that entered you, and does not deal directly with candidates or parents. If you are a private candidate, your enquiry goes through the centre where you sat the exam.
How long does a Cambridge enquiry about results take? Cambridge normally issues an outcome within 30 days of receiving the enquiry, and your school receives an acknowledgement letter within about two working days of submission. If no acknowledgement arrives in that time, ask your exams officer to contact Cambridge, because it may mean the enquiry was never received.
Does a retake grade replace my June grade? No — each series produces its own result, and both remain on your record. Universities and schools generally consider your best grade, but you should check the specific admissions policy of anywhere you are applying.
