Final answer:
Auditing a course allows participation without earning formal credit or a grade, often for professional development or review purposes and does not count toward degree credit.
Step-by-step explanation:
When students audit a course, they participate in the class without receiving formal credit or a grade. Auditing is often done for reasons of professional development or to review material. While you won't earn credit toward a degree by auditing, you have the opportunity to learn about the certification process for a particular field, gain new knowledge and skills relevant to your career, and engage with course material without the pressure of exams and grades. It's important to note that the decision to audit should be made based on individual professional goals and learning needs, as these experiences are designed to enhance professional expertise or personal knowledge rather than contribute to a formal academic record.
