It's quick and easy to get started on a paper like this while you're online.
Tip: If you're already in Word Online, get to college-related templates by going to File > New, and then below the template images click More on Office.com.
You'll be on the Templates for Word page. In the list of categories, click College Tools.
As you work on the paper, you'll probably want to rename it and edit the header with a running head of your own. When you cite sources, you'll want to add footnotes, and then compile your list of references (bibliography). Be sure also to include a table of contents that can update automatically. That way, you won't have to re-type page numbers every time you make changes that affect page breaks.
Work with others on your paper
When more than one person is editing in Word Online, everyone will see each other's updates in the document. For more about how this works, see Work together on a document in Word Online.
Tip: To communicate with everyone who's editing the paper, start a chat session alongside the document.
Turn in a hard-copy version
When you're finished, print out your paper to turn it in. You can do this with the paper still open in Word Online. No need to save it first (that's already done for you).
To print, press Ctrl+P, and wait for the Print dialog.
Note: If you don't see a Print dialog box, click the link for opening a PDF version of your paper. From there, use the PDF program's Print command.
