This is a question I was about to ask a few days ago because I did a search for "GPA w/o" and the system returned 0 results. I ended up figuring it out through AADSAS though. That might be why it is asked so often. Also, when I tried to do a search for "+ -" and "A+" to find posts on those debates, it came up empty. This is because + and - are not recognized as search terms, they are boolean operators that modify the search. That's why no one can find these threads it unless they go out and do a Google search and find it that way.
