1" margins set for all sides.
Exceptions set by instructor. Some possibilities:
1/2" indentation used at beginning of paragraph, use <Tab>
Times New Roman (or equivalent) set to 9 or 10 point.
Justified alignment (type is spaced automatically that it is spread across a line. Will not have a "jagged right edge".)
[Consult with your instructor as to expectations for font typeface and size]
Single spacing used throughout the paper.
Page numbers are placed in one of four places. The important thing is to be consistent and follow your instructions.
In all cases, at least 1/2 inch from the edge of the page.
Headings and subheadings should appear throughout the work to divide the subject matter into logical parts and to emphasize the major elements and considerations. Parts or sections may be numbered, if desired, but paragraphs should not be numbered.
