Use a reasonably-sized font: either 10 characters per inch or a 12 point font. And choose a font that is easy to read rather one that is decorative: "Arial," "Lucida," "Modern," "Palermo" or "Times New Roman" are some good choices. Scripted fonts are hard to read even if they do make your paper "look nice"; it is the content of the paper that is most important, and making it easy for your readers to understand that content is always a good choice.
Sheets of paper should be stapled at the upper left-hand corner. Use a paper clip if no stapler is available. Do not use a pin or fold the paper. Unless specifically requested by your teacher, do not hand in your paper in a folder, a binder, a plastic jacket, rolled up with an elastic band around it, or tied with a ribbon or a string. Do not spray perfume or cologne on your paper or use scented paper. And NEVER hand in your research or term paper in loose sheets even if the sheets are numbered and neatly placed in an envelope or folder.
