I am 1/4 Hispanic (my grandmother is Mexican) and I'm about to begin applying to colleges. Should I still mark the Hispanic category on applications even though my race is white and you can't tell I'm Hispanic by looking at me?

I put "Human" and a😃.

Its your choice. Know this you can't be interchanging your category on college applications.

I would suggest you choose either

1. Hispanic

2. White

Finally "Outside Looks" doesn't  determine your ethnicity. I know many people who don't look like their "Race".

I would just mark "White" ! Since that's what you mainly are. I'm 100% Italian with a darker skin tone but I never see Italian on any forms so I always just mark "White". I think that's dumb that they even ask that and it should be done away with.
