Odd, I'm also a Comp Eng grad and my experience was exactly the same - including the cross campus bit. I went to University of Nebraska - Lincoln.

There was still definitely a fair amount of real cheating though. Especially during the online classes of COVID.

Most of the cheating I saw was from classes that had clearly had difficulty creep up year after year due to un-caught cheating though, and had truly awful professors. Chegg, I think, has really inflated the difficulty for the hosest people.

I think the most common cheating i actually saw in engineering was group work where only 1 person did anything. Hell, I have an example on my GitHub where my partner made one commit with one line of code which I then had to redo anyway.
