How can I tell if my computer and internet connection will work well for the online classes?

My mic or webcam won't work, what do I do? (give some troubleshooting ideas)

I cannot enter the classroom, what do I do?

(A- if it is not 10 minutes prior to the scheduled class, please wait until that time and then refresh your webpage.  B- If you do not have access to a class you registered for, please contact Photini)
