Uploading essays via Document Upload System

Hi guys. I didn’t submit my essays along with my Apply Texas app, so I need to submit them via Document Upload. I have a few questions:

-Double spaced or single spaced?
-Does the essay need to be condensed into a single page? It says “if your essay is more than 1 page length, make sure it’s uploaded as a single document” but I don’t know what that means.

Anyone know?

I’d go with double spaced, to be safe.

By “single document”, I’m pretty sure just make sure your essay in in one document (pdf, doc, etc.)

My impression is you can go back to Apply Texas and submit your essays from there.
I haven’t tried it so I am not 100% certain.
