Most courses require students to write papers using the Student Style. Do not use the Professional Style paper unless your instructor requests you to do so. If you are unsure which style to use, ask your instructor for clarification.
The key differences between Student Style and Professional Style are the Title Page and the Abstract.
Student Style papers do not require an abstract, whereas Professional Style papers do require an abstract.
An abstract is a brief, comprehensive summary of the contents of the paper and is accompanied by a list of keywords.
