I am contemplating a mechanism where mass entrance examinations will be conducted fully online with zero human supervision. But the main hurdle seems to be mass cheating.
How can I overcome this problem in case of, say, thousand students sitting for their exam on the same day at the same time? How can I make sure they are not cheating?
The camera can be an option, but, is it possible without the camera? And, how do I know that they are not circumventing the camera? For example, maybe they are copy-pasting from a PDF book.
