Online Scheduled (OS)
What It Is: Think of this as a virtual classroom. You'll join your classmates and instructor online, on specific days and times, just like you would for an in-person class, but through a video conference tool. Sometimes, there might be activities that you can do on your own time, too. And yes, you might have exams that you take online with someone watching (proctored) to make sure everything's fair.
Example: Imagine logging into a video call every day at 9:00 a.m. for a 50-minute class. That's what this is like.
