Modeling Classes

I’m sorry about my silly question, but does taking modeling classes count as extracurriculars?

I spent about 6-12 months (or more; I already forgot) taking modeling classes (e.g. Learning how to catwalk, model, proper etiquette, how to give speeches, etc. were all part of the modeling class) at John Casablancas, but I never pursued a career after finishing the class because I value my education over modeling (although I somewhat regret that decision).

I have many other extracurriculars, but I’m not sure if I’m allowed to list “modeling classes” as an extracurricular on CommonApp or any other university application, because although I did spend a reasonable amount of time on it, I never pursued a career in it after finishing.

Thank you in advance!
