So, one of my TAs messed up and accidentally gave everyone in the class (500 students) a participation score instead of just his section. Since I didn't save the gradebook immediately before he did this, am I correct in understanding that there is no way to fix this?
I understand that I can view the entire Gradebook history, but given that there are 12 TAs, 32 discussion sections, and 500 students, that's a lot to dig through (even if I use filters). I don't suppose there is any way to download the Gradebook history, say, into a csv file or something? Even browsing requires time for Canvas to fetch more info (about 10 or 15 changes at a time, which for a class of 500....).
