Hi Hutch,

With math questions, the level of difficulty is much easier to assess, since it's easy to see the work involved for each approach, and it's easy to gauge the complexity of outside-the-box thinking. Verbal questions are a different story, and students often disagree with assigned levels of difficulty.
That said, for a while now, we've been thinking of labeling our Verbal questions in this manner. Perhaps we'll do so.

Cheers,
Brent
