Hey guys, first time posting, have a problem in hands, bought a TI NSPIRE CX CAS for college, used it just fine in plenty of exams with the help of press to test mode, however, i want to change course, so I need to retake my high school math exam, and the NSPIRE CX CAS is not allowed, and they're not budging despite it having press to test mode enabled, when we get in the room to take the exam they go to Settings/State /About and if it says its a TI Nspire CX CAS they won't allow you to use it, I need help changing that, I already tried instaling the Nspire CX's OS on it, but it didn't change, I want to know what I can do to be able to use my calculator on the exam.
Thank you in advance.
