Do I have to upgrade at the beginning?
You're welcome to begin a course in the audit track, then upgrade to the verified track soon after the course begins. We recommend upgrading as soon as possible so you can access the graded assignments needed to progress towards earning a certificate.
To find the specific deadline for your course, go to the course Home page, and then locate Upgrade to Verified Certificate under Important Dates.
