It's closer to exposing a first year CS student who has never touched a computer before to Windows, when the work is supposed to be done on Linux, and the TA is hemming and hawing, and insists that the reason the sudo command isn't working is because the student is not following the steps correctly.

It's a problem that's obvious to diagnose... If you already have passing familiarity with the material. Most people do not have passing familiarity with electronic components when they step into an engineering program.
