No. Such things were unheard of. As a professor I tried to institute them, but two things worked hard against it. (1) It was a commuter school, so getting people together outside of class was very difficult, as they didn't reside there and they had other places to be. (2) The concept of what to do in a study group was completely foreign. The social pressure to 'behave,' that is, be a good group member, do your share, and so on, wasn't particularly strong. In effect, like a lot of things, it benefited those who least needed the benefit. It also hurt them (they were often the same people who had important other stuff to attend to). Once it went from mandatory to optional, it died.
