Hello!
Webinars are live classes. If you missed a webinar, you can contact the instructor to see when they will be lecturing on that same topic again. You can contact the instructor via the help center of your student portal. Please include the name and date of the webinar that you missed. All instructors cycle through their material. If you miss it on the first time, you can usually catch it later.
Good Luck in your program!
Dr. Amanda
