I know there are many ways to create an extra credit assignment, but I still haven't found one that's a great fit for me.
I want to have a discussion forum post that adds as much as an extra point to the student's final average. Could I create it as a zero point assignment, but still give a point to those who complete it? (Essentially overriding the zero with a 1 in gradebook?)
My purpose is to be able to add a point to some students' grades without causing a "ding" to the grades of those students who don't do the assignment.
