A "course of study" is well defined in the attached letter that I provided the link to above: Here again ==>

quote:
The term "Course of study" implies a focused program of classes, such as a full-time course load leading to a degree,
or in the case of a vocational student, some type of certification... Courses with more substance or that teach a potential vocation,
such as Flight Training, would be considered part of a "course of study" and
would thus require approval or a student status.
So go form your own opinion.
