Classic quiz erased student answers when settings were changed
I gave my students the opportunity to do an extra credit quiz. But I set it up like a standard graded quiz and it was bringing students' grades down who didn't opt to do it. SO I changed it to a graded survey and when I did it erased all of the students' quiz responses so now I can't grade them. I tried changing it back but it didn't help.
Is there a way to recover the students' responses?
