That is absolutely wild.
When I was at uni (2016-2019), you had to leave all of your belongings behind in a designated area, and only carry a clear/transparent container with your pen(s) to the exam room. You could optionally bring a clear water bottle (label removed.)
If you ask to use the bathroom, there is no opportunity to go back to your belongings.
You're right, but the absolute potato of a camera that was in the Nintendo DSi somehow made everyone look good ๐
