I had an exam today, I had brought my a level calculator by accident (fx-991ex) and I had told the invigilators about this to ask if they had a spare calculator and they told me they don’t and to just write that model name on the exam envelope and do the exam.

I checked online and using calculators that aren’t permitted (fx-83GT,85GT) is considered academic misconduct. I emailed my department about this situation but I cant help but worry that my whole exam can be disqualified, what are the chances of this actually occurring?
