Basically, don't get involved with exams either as an instructor or a student.

Why? Exams hurt all that encounter them (including teachers, markers and even successful students).

And they're pointless by their own terms because knowledge can't be measured.

Really? Because I found that my inability to do matrix math on my second Math 100 exam corresponded pretty well with my lack of understanding about how matrix math worked.

Good point, but there is context missing.

Are you interested in matrix math, or were you merely trying to pass an exam?

Alternatively, if you are interested in matrix math, did the fact that you had to pass an exam make it harder to learn?

Reading comprehension fail.

Probably related to why you do so poorly on tests.

"Tests are life. Rites of passage. They can be good, they can be bad. They should be learning devices. Take as many tests as you can. Take the CLEP tests. Have your tutor give you tests."

From the best self-education book I have read, and I have read lots of them, This Way Out, published in 1972.
