That depends on the complexity of your work. You must be familiar with your department reference style, the SDSU formatting rules, and be an adept Microsoft Word user with regard to the Thesis Template (i.e., you must know how to import your document into the template, apply/remove template styles, change page orientation without losing proper pagination placement, generate a table of contents, work with different types of page breaks, etc.).
If you are concerned about getting the SDSU formatting rules right and graduating on time, you may want to consider the formatting services offered by Montezuma Publishing.
