You take an unapproved calculator into your Mathematics exam. The calculator has CAS functionality, which is not allowed as it can provide an advantage. You reason that it’s your teacher’s responsibility to make sure you’ve got the correct calculator.

Short answer: No — bringing an unapproved CAS calculator is your responsibility, not just your teacher’s. Even if the teacher should check, exam rules are on you to follow. Carrying a prohibited device can lead to your script being invalidated or disciplinary action.

What to do now / practical steps

- Check the exam rules immediately (course syllabus, exam board, school policy) to confirm whether CAS or that particular model is banned.
- If the exam hasn’t started, contact the instructor/exam supervisor right away and ask whether your calculator is allowed. Explain and follow whatever they instruct (swap it for an approved device, leave it outside the room, etc.).
- If the exam is in progress and you are discovered with the device: be calm, cooperate, hand it over when asked, and follow the invigilator’s procedures. Don’t try to hide features or power it down to conceal evidence — that looks like cheating.
- If you are penalized and believe that was unfair, use the formal appeals/complaints channel afterwards. Collect documentary evidence (messages, published allowed-device lists) to support your case.

Why this matters
- Exams (especially formal/board exams) have strict rules because CAS gives an unfair advantage on algebraic manipulation, symbolic integration, etc. Even if the teacher should enforce allowed lists, the student is generally held to the rules.
- Trying to shift responsibility or conceal the device will worsen the situation.

Prevention for the future
- Buy an approved calculator model (check the approved list for your exam board) or use a non-CAS model.
- If you ever need to use a processor with CAS for coursework, get written permission in advance from the instructor/exam board and carry that written approval to the exam.
- Keep a backup approved calculator or know how to access one at school on exam day.

If you want, I can:
- Check a specific model for CAS status (tell me the model number), or
- Draft a short email you can send to your teacher/exam officer asking for clarification/permission.
