Your paper should include an introductory paragraph(s), a body expressing your main points and a concluding paragraph(s) that summarizes your point.
Consult a citation style manual or online guide for specific instructions on how to cite your sources. It is common practice to insert a parenthetical note. For example, if you are referring to an article written by Tim Johnson written in 1999, then insert (Johnson, 1999) after the text that refers to the article. The parenthetical citation should come at the end of the sentence in which you have included the quote or summary. Remember to include complete information on this source in your Bibliography or Works Cited list.
Run a spell check and grammar check - either the options built into Microsoft Word, or a website like Grammarly. Consider each of the suggested replacements carefully.
Read your paper out loud to catch errors you've missed.
