I have search through the help topics and none of them are helping.  I've read the instructions for fudging points to change a quiz grade for a student, but even though it looks like I can do this in Speed Grader, when I hit "update score" it will not save.  The score is "greyed out" by the student's name (in speed grader).  Not sure if that is why and cannot change it.  This quiz closed awhile ago.  Does it need to be reopened?  

Not sure what to do but I have policy for those who took it late (online) - they should lose some points.  How do I reduce their score for submitting this quiz late?

Thanks to anyone who can help!
