Being able to choose the correct answer in a test environment by process of elimination or similar methodology is a useful skill to have in some non-test circumstances, but it’s not a great test of domain knowledge.

Anecdote: I recently did some tests where I read a bunch of material before hand and used a combination of short term memory and multiple choice trickery to pass with flying colors, but I still don’t have any real knowledge of the subject area. I barely remember any of it, other than a few bits of jargon.
