If you've tried all of the above and none of them worked for you, reach out to the Online Instructional Specialist, Brandon Crane. If none of these steps worked, it's usually best to meet so I can see your screen—whether in-person or over Zoom—so feel free to go ahead and book a 15- or 30-minute appointment with my scheduling link!
