Can someone tell me how the wait list works. I'm on the wait list tomorrow and am wondering if I should just show up or wait for a text?

I've been a member for right around a month. Since then, the instructor was late, and two missed their classes. Is this normal for instructors to do this? I understand life happens and it's possible, but this seems like a lot in just a month.
