As one MBA wrote, “Those who advance quickly in my company are those who write and speak well—it’s as simple as that.” But while writing is always a valuable skill, writing works in different ways in different disciplines. As you prepare written assignments for various courses, then, you will need to become familiar with the expectations, vocabularies, styles, methods of proof, and conventional formats used in each field.
