If you're taking a class in a subject you've never studied before, be sure you take a moment to find out what format you should use for your essays in that discipline. For example: should you be using MLA or APA style? Double or single-spaced? Before you start the assignment, check your assignment sheet and/or ask your professor. Once you know what format you're using, resources like The Everyday Writer and the consultants at the Writing Center can help you learn more about its particular requirements.
