Not that in all likelyhoods, teaching for mundane abilities (such as Artes Liberales) would likely not be 1-to-1. There are always apprentices (or even other magi) that need to be taught. If such a class is taught at all on that specific season.
And I agree that Dureenmar is not known for its many mundane teachers, nor are they original thinkers. A little something to do with a powerful aura warping the mundanes, I believe...
