Yeah, I had them my professors didn't let us use them. Trying to sneak a look would lead to cheating and risk expulsion if caught. And cameras in some classes and multiple people like TAs walking around.

If laptop or tablets were used for exam taking they made us use programs like examsoft that locked down the hardware so you couldn't access internet, files, or other programs until you finished the exam.

Or it was open note, open laptop, internet, so professors didn't care at all what was used.

So all I see is zero effort of exam proctoring and then being baffled that students are cheating despite making the environment very easy to do so. It's like you are afraid to take away or restrict electronic usage during exams or the concept is so foreign to you.
