Hi I'd be so grateful if someone could help me out here.

I've registered for the GRE some time back and now when I was looking
through my old confirmation email, I realized that I've included my first and last name
but not my ethnic name which appears on some of my certificates/ Identification. From what I've seen on the web ETS doesn't allow me to add that in or change my name. I thought about re-registering but (ouch$$$).

Plus I think it'll be odd for adcoms to see my first and ethic name squished together without spaces...
Any thoughts? And thank you so much!
