The problem is that only works at the advanced courses. However people need to learn the basics before they reach that level, specially when they are starting and are in many regards below the LLM's baseline.

Blue books.

Need to type? Computer labs (“test taking labs” idk) are back baby. Simple machines, no Internet.

Pretty sure that solves 90% of the testing problem. If somebody is overly reliant on LLM’s and refuses to learn, they’ll pay with their grades on the big assignments. Bummer for teachers who don’t love blue books, but I’m sure it’s a hell of a lot better than trying to sniff out LLMs and constantly mistrusting your students.

Says who?

Your work will be ‘graded’ by other humans who don’t know what they are talking about, or an LLM which will assume the median answer is correct?
