Well after a bit more digging, I was wondering if you had any thoughts on this.

Under the section
A. Permission to Engage in Activities Other Than Permitted by the Status of Sojourn
Stated:
ㅇ The holder of F-1(visiting and joining families) or F-3(dependent families) status doesn't have to get additional permission for an education or language course below a high school level educational institute.
Does this mean someone on F-3 can TAKE high school courses and below or can TEACH high school courses and below. Talk about not too clear, wheeeee.
