Affiliate Marketing Secrets

Ok, so the application is asking me
1) Are you Hispanic or Latino?
Yes or no
2) Regardless of your answer to the prior question, please check one or more of the following groups in which you consider yourself to be a member:
American Indian or Alaska Native
Asian
Black or African American
Native Hawaiian or Other Pacific Islander
White
Ok, so the problem is that I consider myself only hispanic and none of the other racial groups. I am not european. I am not african. I know I’m not asian. I’m not from the islands either. I’m not affiliated with any native american tribes. So what the heck am I supposed to answer?

I ask because, although I do a lot of “activities” outside of school, they are not necessarily school-affiliated activities, or with clubs. Like, I like to play the bass guitar & sing, and paint & draw, and study a lot of subjects on my own time. And writing is absolutely my passion. BUT these aren’t school- or club-affiliated activities.
So, in order to list this stuff on a college application, do they have to be sponsored by the school in order to be extracurriculars?
Although I am in a few clubs at my school, I would like to express to colleges how I spend my time in activities that aren’t school-related.
So, what qualifies an extracurricular activity? Is it truly just extracurricular, in that, it’s something you do that is EXTRA, or does it have to be like a sport, or with a club, or with the school?
