Degree Works allows you to run a one-time audit based on a hypothetical new curriculum. For example, you could see what the audit would look like if a second major or minor was added. You could also see what the audit would look like if you changed majors.
The "What If" link is just underneath the Student Header. The menu that appears prompts you to enter a catalog year and a program. After you enter the program, the rest of the information should populate automatically. If you wish to see a hypothetical audit with a second major or minor, you must first enter your current program information (in this case, do NOT check the box for current curriculum), and then underneath, enter the additional major or minor in the "additional areas of study" section.
