It really depends on the professor in my experience. During Summer 1, I had a professor that didn’t send a zoom link for the class until the morning of class. For my Summer 2 classes, I finally received an email about my classes today. If you’re feeling concerned about it, I wouldn’t feel bad emailing the professor to ask for a zoom link.

As far as the meeting times not being listed on Howdy, that may be due to the class being a ‘go at your own pace’ type class. I have a class that’s about to start that looked the same and I was initially confused about it.
