Courses are offered at one or more credit levels: undergraduate, graduate, or noncredit, so noted in course descriptions.
Undergraduate and graduate credit
If you want to receive academic credit and grades, you must register for undergraduate or graduate credit. You do not have to be an undergraduate student to take a course for undergraduate credit, nor are you required to have an undergraduate degree to register for graduate credit. Students taking courses for graduate credit may have additional or different assignments and generally are required to perform at a higher level than students enrolled for undergraduate credit.
To audit courses, you must register for noncredit if it is available. Courses that do not have a noncredit option may not be audited. Noncredit status means you may not take final exams or submit final projects. In some courses instructors will accept and correct other written work from noncredit students, but they may not assign grades for that work. As a noncredit student, you do not receive grades or academic credit, but the courses do appear on your transcript.
You may change your credit status until the course and credit status changes deadlines. See the calendar for dates.
