Virtual Class Question

I'm enrolled in a virtual class that starts tomorrow but I have no idea how to join the video call. The course opens on Blackboard tomorrow morning, so i'm hoping i'll have access to the meeting code when it does, but I hate not knowing for sure. How does it usually work? I'm dual enrolling, and have had to jump through a lot of hoops to do this, so I'm worried that I'm missing an important step or something.
