I'm pretty sure the etiquette professor has been played a number of times, but I'm not completely sure how an IC class would be conducted.

• Would lessons mix-gendered? Am I right in remembering that they are?
  
• Would lessons be demonstrative and hands-on, or mostly theory and book-based?
  
• Is it intended to supplement the etiquette teachings that children would receive at home? Or would it be comprehensive and begin with the bare basics considering that all students, regardless of background and gender, have to take it?
  

I'll probably think of more but these are the ones that are bugging me~
