> I am thinking of student essays and prose answers to exam questions.

Dude/Dudette, circuit theory can't be further than it already is from prose essays and and open-answer questions.

As I mentioned, part of the strategy was to use simple numbers (think of stuff like 1, 2,-1, pi, stuff like that) because the hard part of the exam was not in numbers and/or raw computation.

So basically if you can read numbers, you can see what's been done there.

And I expect an engineering professor to be able to read numbers.
