"Uh... right, got to state all the things that of course everybody already knows.  Nobody gets to be a Professor at Cowcorn unless they've maxed out all the Skills in the basic Teacher Class.  They've all got tier-2 skills, and some of them have maxed those out and gotten tier-3 Teaching skills, which is one of the requirements to be a Magister.  Another requirement is that you have to be able to raise the Skills of your students quickly."  Haroun's voice takes on an awed tone.  "Magister Sting charges roughly nothing for Upgrades except to very rich students, but she's... the orichalcum guildplate SS-rank version of a Professor.  She has tier 4 teaching skills.  I took a math class from her once and learned all of the basic Inverse Probability skills in two hours.  Cost me twenty copper for the Upgrade.  If she moved to the capital of a major country and charged what the market would bear, she could get paid in mithril."
