I entered grades, but after I was completed I realized the number of points I had entered for the amount possible was incorrect. When I changed this, it took out all of the points I had entered each student received. Is there a way to get that back?
If you are using PT Pro and have clicked "save," no. There is a "point-in-time-recovery," also known as a Flashback, but it would never be done for lost assignment grades.
