What are "Interdisciplinary Studies" in HS on the Collegeboard Website?

I’m trying to register for the SAT and create my profile on the Collegeboard site and I’m not sure what they mean by ‘interdisciplinary studies’ on the form… they ask how many years in high school you did in this category. What types of classes would these be? Personal Finance and Entrepreneurship? Foreign Languages?.. I don’t think so because there’s a different category for that.

I can’t seem to find the answer to this question online :confused:

But honestly, I don’t think the CB profile is really that important…

I still don’t get it, but I realized I didn’t need to do any of that to actually register. I don’t care about the CB profile, I just wanted to do the registration. ; )
