What can a student bring into a Cambridge IGCSE examination in 2027, and do the same calculator, mobile-phone and smartwatch rules apply to Singapore SEC? The safest answer is to use the current instructions from the exact examining authority and entering centre. Cambridge IGCSE candidates must obey Cambridge’s exam-day rules and the relevant subject syllabus: unauthorised electronic devices, notes and many personal items cannot be brought into the examination room. Calculators are permitted only where the syllabus and paper allow them, and their features must satisfy the rules. Singapore’s national Singapore-Cambridge Secondary Education Certificate (SEC), beginning in 2027 under Full Subject-Based Banding (Full SBB), has separate SEAB instructions and approved-device lists.
For parents searching “IGCSE calculator allowed 2027”, “can I wear smartwatch IGCSE exam”, “Cambridge phone in exam hall”, “IGCSE pencil case rules”, “SEC calculator list”, “what happens if I am late to an IGCSE exam”, the issue is practical rather than academic. One prohibited device can create a serious examination-security problem even if the candidate never intended to cheat. A child who studied diligently should not lose concentration or face malpractice proceedings because the exam bag was not checked.
The answer in one minute
- Cambridge mobile phones and smart devices: do not take them into the examination room; the centre must tell students where to leave them. Cambridge treats unauthorised possession as an exam-rule breach.
- Watches: the Cambridge Handbook 2026 added watches to its unauthorised-material examples; leave watches outside as directed by the centre instead of assuming a non-smart watch is automatically acceptable.
- Calculators: check the exact subject and paper. Cambridge IGCSE Mathematics 0580 has non-calculator papers; Cambridge IGCSE Computer Science 0478 prohibits calculators in both papers of its 2026–2028 syllabus.
- Calculator features: Cambridge generally prohibits symbolic algebra, stored text and remote communication, with specific exceptions only where a syllabus permits them.
- Cambridge dictionaries: a simple translation dictionary may be permitted in certain non-language IGCSE exams unless forbidden by the syllabus, but electronic dictionaries are prohibited. Never infer the permission for a particular subject without checking.
- Singapore SEC: use SEAB’s approved calculator and dictionary lists, current examination-year rules, the subject syllabus and the school’s candidate notice.
- Examination clashes and late arrival: report immediately to the exams officer; full centre supervision and late-arrival decisions follow official rules, not personal arrangements.
- Best action: review the candidate’s subject entry, permitted materials, official paper time and centre’s exam-readiness instructions the day before every component.
Why Cambridge IGCSE and SEC exam rules must be kept separate
Cambridge IGCSE is an international qualification administered through Cambridge International Education and its authorised centres. The 2026 Cambridge Handbook governs its examination administration and the centre must follow Cambridge’s current handbook and any subsequently issued updates. Different IGCSE subjects can require different materials, question-paper formats and component arrangements.
Singapore SEC is a national examination jointly examined and awarded by SEAB, MOE and Cambridge International Education. Under Full SBB, students take different national subjects at G1, G2 and G3, and the SEC records their subject levels. The shared Cambridge involvement does not turn the international IGCSE handbook into the entire national SEC candidate rulebook.
For example, a Cambridge IGCSE 0580 Mathematics paper and a Singapore SEC G3 Mathematics K310 paper can both involve algebra, but they are not the same examination. The candidate’s calculator permissions, paper codes and reporting arrangements must be taken from the correct authority and subject.

Common items: what a family should check
| Item | Cambridge IGCSE | Singapore SEC |
|---|---|---|
| Mobile phone / smartwatch | Unauthorised in examination room; surrender or leave outside under centre instructions | Use current SEAB candidate rules and school instructions; do not carry unauthorised devices into an exam area |
| Ordinary watch | Cambridge 2026 Handbook lists watches as unauthorised materials | Check the national current notice; don’t assume Cambridge wording is the SEAB rule |
| Calculator | Only in permitted papers, subject to Cambridge functionality restrictions | Only when the national subject permits and under SEAB calculator rules |
| Dictionary | Simple translation dictionary may be allowed in specified non-language IGCSE papers, subject to rules; no electronic dictionary | Only as stated by the current SEAB approved lists and subject instructions |
| Notes and books | Unauthorised unless the syllabus and paper explicitly permit particular materials | Follow official national exam instructions; do not bring unauthorised references |
| Food, drink, personal items | Subject to centre decisions and rules on packaging, labelling and disturbance | Follow SEAB and centre instructions, including approved access arrangements |
The principle is straightforward: the examination centre needs to know that no candidate can obtain an unfair information advantage or communicate with people outside the assessment. A personal item can be prohibited for security reasons even when it was brought innocently.
Why “I did not use my phone” is not enough
Cambridge classifies possession of unauthorised examination materials as a breach of its regulations. Its malpractice guidance includes mobile phones, electronic devices, unauthorised notes and other prohibited materials among examples of candidate malpractice. A phone being on silent, switched off or unused does not automatically make it authorised to remain in the examination room.
Make the safe routine physical: before entering, check pockets, jacket, pencil case, calculator cover and any personal belongings the centre allows into the venue. Put phones, watches, earbuds and other non-permitted items in the place assigned by invigilators. Do not carry a smartwatch simply because it looks like an ordinary watch.
The same caution applies to smart glasses, devices capable of storing or communicating information and unexpected accessories. A candidate may not realise that a seemingly ordinary gadget has a prohibited feature. When uncertain, ask the invigilator before the examination begins rather than waiting until it is discovered at the desk.

Which Cambridge IGCSE calculators are allowed?
Cambridge’s general rule is that calculators can be used unless the subject syllabus or question paper prohibits them. Where permitted, the calculator must not have disallowed functionality such as symbolic algebra manipulation, retrieval of stored text, communication with another machine or other features prohibited by the handbook. Cambridge’s calculator FAQ also lists restrictions on graphing displays unless the specific syllabus authorises an exception.
That last qualifier matters. Cambridge IGCSE International Mathematics 0607 has explicitly prescribed graphing-calculator arrangements under its syllabus, while many other IGCSE papers do not permit that category of device. Parents should not conclude that every graphical calculator is banned in every Cambridge subject or allowed in every Cambridge Mathematics subject. The syllabus-specific rule controls.
Even if a device is allowed, the student must show the reasoning required by the mark scheme. A calculator displaying the right final value cannot replace algebraic working where marks depend on the method. Equally, a calculator that can solve algebra symbolically may be unsuitable for a paper requiring the student to demonstrate independent manipulation.
Cambridge’s official calculator guidance says the examinations officer is the correct point of contact about a particular model and paper. There is no safe rule that a calculator bought for one examination board will be acceptable for every other examination.
Three IGCSE subjects, three calculator decisions
Cambridge IGCSE Mathematics 0580: the 2025–2027 syllabus has a Core non-calculator paper and calculator paper, and an Extended non-calculator paper and calculator paper. A student who brings a calculator expecting to use it throughout will find the non-calculator portion a genuine separate assessment of fluency.
Cambridge IGCSE Additional Mathematics 0606: in 2025–2027, Paper 1 is a two-hour non-calculator examination and Paper 2 is a two-hour calculator examination. Basic algebra, exact values and manipulation must be strong enough to work under the specified conditions.
Cambridge IGCSE Computer Science 0478: the 2026–2028 syllabus states that calculators are prohibited in both its Computer Systems and Algorithms, Programming and Logic papers. Students should not assume that a computing subject automatically allows a calculator because they are studying technology.
Check 0580, 0606 and 0478 before creating practice conditions at home.
How Singapore SEC calculator rules differ
SEAB maintains an official list of approved calculators and dictionaries for national examinations. Families should consult the current approved list, the actual SEC subject syllabus and their school’s candidate notice. The national requirements may restrict calculators with stored information, communication capabilities or advanced functions. A model approved for one national examination may not be permitted in a paper that bans calculator use.
Singapore’s historical examination guidance also distinguishes ordinary scientific calculators from graphing calculators authorised for certain A-Level subjects. A family must not import Cambridge IGCSE International Mathematics graphing-calculator permission into Singapore SEC G3 Mathematics. Each authority controls what its examination assesses and which tools are allowed.
Do not base an equipment purchase only on another parent saying a model “worked last year”. The school examinations officer and official current list are more reliable. The student should know the approved calculator’s basic functions and power requirements before exam day rather than trying an unfamiliar device for the first time during an actual paper.
Official source: SEAB approved calculators and dictionaries.
Can an IGCSE student bring a dictionary?
This has an important qualification. Cambridge’s Handbook allows a simple translation dictionary in certain Cambridge IGCSE examinations, except language exams or where the subject syllabus prohibits it. A simple translation dictionary gives word-to-word translations rather than detailed definitions. Electronic dictionaries are not allowed in its examinations.
Therefore, “dictionaries are always banned in IGCSE” is too broad, but “any dictionary is allowed” is equally wrong. Ask the examinations officer about the exact subject, qualification, permitted dictionary type and any applicable local restrictions. An annotated dictionary or electronic translation device can violate the rules even when a clean, simple paper dictionary would have been authorised for that particular paper.
For Singapore national SEC, use SEAB’s own approved dictionary list and subject instructions. Cambridge’s international dictionary rule does not automatically apply to SEC subjects simply because both qualifications mention Cambridge.
Worked example: a correct calculation under different paper rules
Imagine an original question: “A $150 item rises in price by 12%, then receives a 12% discount on the increased price. Find the final price.” The first stage is 150 × 1.12 = $168. The second is 168 × 0.88 = $147.84. The final price is below the starting price because the increase and decrease use different bases.
In a calculator-permitted paper, the student may use an allowed device for the arithmetic, but still needs to select the multipliers correctly and show the required working. In a non-calculator paper, they may calculate exactly: 168 × 0.88 = 168 − (0.12 × 168) = 168 − 20.16 = $147.84. The underlying understanding does not change merely because the permitted tool changes.
Ask a harder variation: “What discount after a 12% increase would restore exactly the original price?” The increased price is 1.12 times the original, so the necessary multiplier is 1 ÷ 1.12 = 25/28. The discount fraction is 1 − 25/28 = 3/28, or approximately 10.714%. A student who simply answers 12% has not recognised the changed reference base. Calculator availability cannot repair that misconception; teaching must address the concept.
What happens if two IGCSE papers clash?
Cambridge uses a global timetable with time zones, Key Times and formal Full Centre Supervision arrangements to keep examinations secure. If papers clash, the centre handles the scheduling under Cambridge’s published examination rules. Students must not rearrange start times themselves or leave the supervised group to communicate with friends outside the centre about a paper.
Cambridge explains that Full Centre Supervision means candidates remain under invigilation until the relevant Key Time. Depending on the stage, students may be permitted to consult books or talk with others under supervision, but they cannot access phones, the internet or people outside the controlled group. The centre’s instructions determine the actual permitted activities and movement.
If a candidate has a genuine clash, the family should tell the exams officer well before exam day so the school can make permitted arrangements. The final centre timetable is the authority, not an informal list copied from a group chat.
Official reference: What Full Centre Supervision means.
What if the student is late or an unexpected disruption occurs?
Notify the examination centre immediately. Do not tell a late candidate to enter an exam room without permission or assume they may automatically make up the paper later. Late-arrival handling, train disruptions and unforeseen events are governed by the relevant examination authority and centre procedures. The supervising officer decides which official process applies.
SEAB has publicly described protocols for late arrival, listening-comprehension interruptions and other examination problems. Its guidance says examination personnel are briefed on standard procedures and refer complicated cases to SEAB. That is safer than a student’s improvised decision, especially when many candidates may be affected by a transport or technical disruption.
For serious illness or other qualifying adverse circumstances, a special-consideration process may be applicable. It is not a guarantee that missing an exam will automatically produce a predicted result. The school must follow the current official procedure and any documentary requirements.

The day-before checklist that prevents avoidable problems
- Confirm the exact qualification: Cambridge IGCSE, Pearson International GCSE or SEC. Keep separate instructions for each.
- Confirm the subject and component: the paper code and whether it is written, oral, practical or digital.
- Read the current timetable: exam date, reporting time, entry documents and examination centre location.
- Review the materials list: permitted pens, pencils, mathematical tools and paper-specific equipment.
- Check the calculator: allowed paper, approved functions, power condition and any memory-clearing instructions.
- Remove unauthorised items: phones, watches, earbuds, notes, electronic devices and material in calculator covers or pencil cases.
- Prepare identity documents: use exactly what the centre requests; do not invent an alternative.
- Plan transport: know the route and a reasonable backup in case of disruption.
- Protect rest: sleep and ordinary meals support attention better than exhausting last-minute revision.
- Know who to contact: save the examinations officer’s official number for emergencies, but do not carry the phone into the examination room.
How to behave when something looks wrong in the paper
If a student thinks a question paper has a missing page, unclear instruction or printing problem, they should raise their hand and notify the invigilator without disturbing others. They should not communicate with another candidate or use an unapproved device to check a question online. The exam authority has procedures for recording and escalating genuine problems.
If a candidate realises that a prohibited item is still in their pocket before the paper starts, the safest action is to notify the invigilator immediately and follow instructions. Do not attempt to hide the item or quietly transfer it to another student. The centre will decide how to handle and report the incident under the official rules.
Exam security protects all candidates. A student who follows the rules accurately should be able to focus on demonstrating their knowledge rather than worrying about administrative mistakes.
Frequently asked questions
Can I bring a smartwatch into a Cambridge IGCSE exam?
Cambridge lists smartwatches and other unauthorised devices as prohibited in the exam room; the 2026 handbook also lists watches. Follow the centre’s storage instructions.
Is a phone allowed if it is switched off?
Do not keep it in the examination room. Cambridge treats unauthorised possession as a rule breach; leave it where the invigilator directs.
Are calculators allowed in every IGCSE paper?
No. Subject and component rules control permission. For 2027, Cambridge 0580 and 0606 each have non-calculator papers, while 0478 prohibits calculators in both papers.
Can I use a graphing calculator in any IGCSE Mathematics exam?
No. Cambridge generally restricts graphing functions unless a syllabus specifically permits them. Check the exact subject and option, including exceptions such as International Mathematics 0607.
Do Singapore SEC students use Cambridge’s calculator list?
Do not assume so. SEAB provides its own national approved calculator and dictionary lists.
Are paper dictionaries always banned in IGCSE?
No universal ban applies: Cambridge allows certain simple translation dictionaries in eligible non-language IGCSE exams. The exact subject and local rules still control.
What if two papers are at the same time?
The exams officer handles clashes under formal timetable and full-centre-supervision rules. Do not rearrange your exam schedule independently.
What if the student arrives late?
Contact the centre immediately and follow the exam authority’s late-arrival procedures. A make-up sitting is not automatically granted.
Are exam rules the same because SEC and IGCSE both mention Cambridge?
No. SEC is a Singapore national qualification administered under SEAB’s rules; international Cambridge IGCSE has its own handbook and subject instructions.
