Chicago Style, APA and MLA are common styles used for writing academic papers. While Chicago Style is popular among business and history majors, MLA is typically used by the humanities. APA is common among subjects related to science or psychology. Any undergraduate student will often have to use at least two of these styles during their academic career. Although reading the rules or buying a writing guide is always an option, viewing an example of the paper is always easier. Details and rules that are confusing in a writing guide are simpler to understand when they are viewed in the context of an actual paper.
