I am using Launchpad for the first time this year and have been "practicing" setting up the course and also taking quizzes, using Learning Curve, etc as "a student." Now, I need to clear everything out and start setting up the class for real. I can "unassign" many assignments, but I can't seem to get rid of Learning Curve or Chapter Quizzes scores. They continue to show up in the gradebook. I guess I just need to know how to get a "clean slate." Thank you!
