If you play around with the application (try copy and pasting), you can see what works and what doesn't. A lot of the time the formatting will get messed up if you copy and paste from word. As Tacmon said above, copying it into Wordpad and then copying from there into the app usually eliminates the formatting problems; however, certain apps are just irritating, and I had to type those in word for word. Just make sure that you read over your essays before hitting submit if you ever copy and paste (or even if you don't... just to be sure).
