Sending in sample writing as exhibit

I’m applying to Elk’s MVS Scholarship, and they have an option to send in “exhibits.” Their examples were copies of awards or newspaper articles that you’re featured in, etc. The only thing I think of to send in along those lines are copies of varsity letters for sports, but I was thinking of sending in an excerpt or two from essay’s I’ve written. I love writing and want to show my ability, but this doesn’t seem to be along the same lines as their examples. Do you think this is a good or bad idea?
