Is there a way to set the upper limit of a grading scheme to say 120%? I've set up a course where the total grade for some of the students is over 100% (I gave them extra credit directly on individual assignments). Now I want to give A+s to those who are over 100%. But it seems like I have to start the range from 100% (instead of say 120%). Is there a way to do that? Any suggestions are greatly appreciated.
