What is the difference between a free course, free audit, and free trial?
A free course keeps its core learning material available at no charge. Free audit access usually removes graded work or a certificate from a paid course. A free trial opens a paid service for a limited period and begins charging after the trial period unless you cancel. This guide excludes trial-only access from the free-course list.
