Questions about UNC Supplements

I am working on the UNC supplements and was wondering if we needed to tie it back to UNC.

Also, should we talk about our major in the supplements?

Also, I decided to write about my art teacher and how she helped me understand the idea of living in the present moment for my community builder essay. I don’t have anything art-related in the rest of my application. Is this fine/okay? It was just a class I took for fun at a neighbor’s house.

Lastly, are there any proofreading websites/people that are good with proofreading supplements?
