Graphing Calculator and Exam Mode in Portugal
1) What is "Examination Mode" and why does it exist?
Exam Mode serves to ensure fairness: it blocks access to stored content (programs, notes, images, documents) while keeping the calculator functional for the exam. Official rules for national exams refer to the use of graphing calculators with this feature in specific subjects.
2) In which exams is it mandatory?
The JNE (National Examinations Board) standard and instructions for 2025 indicate the requirement for a graphing calculator with exam mode in exams such as Mathematics A, Mathematics B and MACS, and also in Physics and Chemistry A (with reference to the applicable official document).
3) What is NOT allowed (critical point of purchase)
The DGE (2024/2025) document, for certain national final exams, states that only graphing calculators that do not have CAS (Symbolic Algebraic Calculus) and are not open-source are authorized, in addition to referring to an illustrative (non-exhaustive) list.
Translation for purchase:
-
If the calculator has CAS protection , you risk being blocked.
-
If it's open-source , the same applies.
-
Look for "standard school" templates and confirm documentation for the school year.
4) "Exemplary list" and validation of your model.
The list attached to the official document is illustrative, not exhaustive . If you have a "different" (or older) template, the official procedure may require you to refresh your memory in the classroom , in the presence of the professor responsible for the verification, in order to take the test.
5) How to enter Exam Mode (without stress)
The procedure varies by make/model. Always follow the manufacturer's instructions.
-
Texas Instruments (e.g., TI-84) : TI provides step-by-step instructions for the examination mode and explains which programs/applications are blocked and the memory is cleared (depending on the family).
-
Casio : There are exam mode support guides for academic years (e.g., 2025/2026) with key sequences and explanations of what becomes inaccessible during the exam.
Tip: Don't leave it until the day of the event. Do a "rehearsal" a week beforehand.
6) What to do on the day of the exam (checklist)
-
Calculator with charged batteries (bring a spare if possible).
-
Active Examination Mode (confirm indicator/LED/warning on screen, depending on the model).
-
If the model is not clearly listed, be prepared for room memory cleanup if required.
-
Do not bring “extras” (cables, cards, accessories) that may cause confusion — follow school/JNE guidelines.
