The summary section (often misleadingly called a “conclusion”) is a short recap of what you have said in the essay. You might want to provide a slightly different version of your thesis statement as the first sentence of this paragraph and then provide a few sentences that sum up what the body section said in support of the thesis statement. The summary section should be only one paragraph long for a short paper, but can be longer for longer papers. (Some instructors, like me, even think that summary sections are unnecessary for short papers.)
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.
