Is it possible to change the point values in the points option for grading? For example, I want to give a student a score of 3.5 or 19.5 on an assignment, but when I choose points, it only gives me 3 or 19 as possible point options. If I use a custom scale I am afraid of messing up the cumulative score.
So is there a way to get a different range of points? If not, do custom scales accomplish this and do they play nicely with other assignment that use point totals?
