Want a fast and easy essay? Follow these three easy steps:

1. Choose a great topic: Scan the list of topics below, or pick something you either know a lot about or would like to learn about. Writing is always easier if you are interested in the topic.
2. Pre-write: Use my pre-writing worksheet questions at the bottom of this article to help guide you through the process of gathering and organizing the information you’ll need to write your essay. It may take 30 minutes (or more if you do research), but when you are done you should be ready to write.
3. Edit: Use your computer's spell and grammar check program, and use Grammarly, which is a free check for errors. Have at least one other person read your paper and give you advice. Finally, read your paper out loud so that you slow down as you read and notice your errors.

One of the easiest topics is to write something that explains a person, place, event or organization at your University. Not only is it easy to get information, you will probably enjoy learning more about your campus or the history of your college.

Methods:

• Interview other students, staff, or faculty. You can use their quotes or stories as evidence for your paper.
• Observe the place you are writing about. Sit down with a notepad or your phone and write down your sensory experiences (what you smell, hear, see, taste, and touch). You can even listen to conversations and observe people. Vividly-written details and personal experience make your expository paper stand out.
• Research by looking at past issues of your college paper or on the college website. You might also find information posted on buildings around campus, the library, or in pamphlets at the visitor's center.
