Above all else, use common sense. If it doesn't look right, change it. It is OK to use the resume templates in Word. Some of the templates, however, are quite unattractive. Past students have started with templates and then abandoned them during the semester.
Resumes require a lot of indenting.
Always use the ruler to move text or set up a table. Never under any circumstances use the space bar to move text over . You will always regret this method for spacing elements as you will almost always end up having to go back and delete the spaces. Tabs are okay, but dangerous. If end up doing any revision or working on your resume in different computer labs, your tabs are likely to wander on the page leaving ugly blank spaces in the middle of your text.
