Some of my past classes formed study groups to discuss the class material and get answers to questions they have. They said it helped them in class and test preparation. You may wish to talk to others in your class to see if there is any interest to form such a group. For what it is worth, we generally held study groups when I was in graduate school. Some were more formal, some less so, but fellow students did discuss course material, ideas for connecting the course concepts, and the like. Sometimes it seemed we learned as much in these discussions as we did in the formal classes.
