Course features differ based on whether you're enrolled in the audit (free) or verified (paid) track of a course.
In the free audit track you will have access to all course materials except graded assignments.
To view graded assignments and earn a certificate if you reach a passing score. Upgrade to the verified track.
Verified track: With this track, you will have access to all course materials including graded assignments. You will have full access to the course material until the course ends. After the course ends, you will still have access to the material, but you will no longer be able to submit graded assignments or earn a certificate.
You will pay a fee when you select the Verified track. Your fee allows us to fund the running of the course, grade your work, and award you a certificate upon successful completion. You can add the certificate to your LinkedIn profile or resume, or in certain cases stack it towards a larger credential, such as a Professional Certificate or MicroMasters® program.
