Zoom DUI classes are classes conducted live via a Zoom interface using Zoom, Skype or other video software. Zoom DUI Classes are scheduled just like live DUI classes are a particular time and date in front of a DUI instructor. So you must be available and in front of your computer during the entire class.
Online DUI classes are different. They are a self-paced class that you can take on your computer on your own schedule. They don't have a particular meeting time. You can log on and log off whenever you need to.
