Open & Free Courses
- Open & Free OLI courses enable independent learners to study a subject on their own terms, at their leisure. Courses are:
- Open & Free courses include only the learning materials:
- No teacher.
- No tests.
- No college credit.
- No certificate of completion.
- *If your teacher gave you a Course Key, do not use an Open & Free course because your teacher will never see your work.
